Spring Design The Easy Way with the Quick Spring Designer

Quick and Easy Spring Design
with the QUICK SPRING DESIGNER

The Quick Spring Designer improves productivity by cutting out guesswork.
This software is aimed at machine designers, mechanical product designers, spring manufacturers and anyone looking for a speedy, effortless method of designing any one of a number of spring types, The Quick Spring Designer bypasses conventional trial and error procedures to produce a spring design in a matter of seconds. In comparison with other spring design software, the Quick Spring Designer departs from traditional methods by only requiring input of the space and performance requirements to quickly produce a design, without the designer having to make a preliminary guess at mean diameter, wire diameter, number of coils, free length and so on. An "Experience Factor" can be input by those skilled in the art who know from experience that allowable stresses can be modified to account for such operations as high-heat stress equalizing, presetting, shot-peening etc. There are many other useful features that are listed at the bottom of this page. The Quick Spring Designer software was introduced in DOS format in 1995 and now runs under Windows 95, NT 3.51 and all later versions. The current Version 4.1 of the software has been extensively rewritten to improve design accuracy, consistency and efficiency. It only requires 11 MB of hard drive space after installation. A 97 page Users Guide is included on the CD. Please feel free to browse through this site to see examples of the software at work. You can click on the navigation buttons above, or the icons below to see how each spring type is dealt with.

The following features are included, when applicable, for most of the spring types in this program: ● English or Metric units ● Life requirement, or estimated life ● Decimal or standard gage wire sizes expectancy ● Static or dynamic load conditions ● Provision for experienced designers to ● Operating temperature compensation adjust permissible stresses to compensate for mechanical or thermal ● Capability of designing from scratch, post treatment or analyzing existing spring designs ● Efficient interaction between the input ● Warning of undesirable results of input and output screens providing values with recommended course of immediate assessment of revisions to correction. ● Printout of input factors, results and the input factors warnings ● Choice of 13 wire specifications, 8 flat ● Graphic printout with editable heading, strip specs, 13 disc spring materials — suitable for ordering springs or for or the designer's own material specs presentation to customers ● Dedicated database for storage of results

Compression Spring Design

Pressing the Spring Analyzer button on the Design screen brings up the Compression Spring Analyst form which can be used to provide the properties of an existing spring or spring design. It can also be used to refine a preliminary design developed on the spring design form. The following information is entered — Mean Dia., Wire Dia., Free Length, No. of Active Coils, at least one Working Height, End Coil Configuration and a Material Specification. You can check the fatigue properties of a spring if a second working height is entered. When the Calculate button on the Compression Spring Analyzer is pressed you are prompted to enter missing values, or correct illogical entries. Then the output screen will appear with, if applicable, message boxes warning of unstable proportions, high or low spring index, height conflict or high stress conditions. They can be cleared by pressing their OK buttons. As with the design mode You can press the Review Input button to return to the input form to make changes if you wish. The immediate interaction between the Review Input button and the Calculate button allows you to switch back and forth easily to see the effect of changed input.

Helical Extension Spring Design

Quick and Easy Spring Design
with the QUICK SPRING DESIGNER

Extension Spring Design and Analysis

Common features are listed at the bottom of the Home Page On the Helical Extension Spring Design form a statically loaded spring can be designed by entering a loaded length and corresponding load and, optionally, any restrictions on spring diameter. For cyclic loading a second loaded length and load, and an expected life are entered. The latter three input boxes are not visible for steady load conditions. The loaded length inputs are designated "provisional". The fixed distance between them and the corresponding difference in loads establishes a spring rate. That, in turn, establishes the initial deflection for the first loaded position which, added to the calculated free length, provides the true loaded lengths. Pressing the Calculate button on the Extension Spring Design form, when all required entries have been made, produces the results screen listing the input values with a report of all the calculated properties. If there are undesirable features in the design such as high or low spring index, too few active coils or potential overstress, warning messages may appear with suggestions for improving the design. On acknowledgement, you can study the results and if you want to make changes, pressing the Review Input will return you to the Design screen where you can edit the input and press Calculate again to see the results.

Helical Extension Spring Design

Pressing the Spring Analyzer button on the Extension Spring Design form produces the Helical Extension Spring Analyst data input form. Data entry includes the mean diameter, wire diameter, either the free length, or the number of active coils, and the hook diameter and hook junction radius. For steady loads only one loaded length is entered. Entry of a second loaded length produces a calculation of the resulting maximum stress and an estimate of life expectancy. The initial tension, if not known, can be omitted and the program will calculate a suitable value. When the Calculate button on the Analysis input form is pressed, if there are undesirable features such as too few active coils, or high or low spring index, or the possibility of excessive stress, information messages appear. After acknowledgement, you can accept the input, or press the Review Input button to return to the data input form. There you can edit the input and press Calculate again to see the results.

Conical Helical Spring Design

Quick and Easy Spring Design
with the QUICK SPRING DESIGNER

Conical Helical Spring Analysis

Common features are listed at the bottom of the Home Page This is one of the two spring types for which no "Design from Scratch" procedure has been developed. Conical helical compression springs are often used to provide a low solid height, or to increase lateral stability, or to provide a variable spring rate. Necessary inputs include the small end inside diameter, the large end outside diameter, the wire diameter, the free length and the number of active coils. For steady loads, the upper loaded height is entered and entry of a second working height allows the fatigue life to be estimated. Pressing the calculate button on the input form produces messages advising of missing or illogical entries that must be attended to before the output screen appears. Then, if applicable, you will be advised of height conflict (solid height greater than input working height), high or low spring index and/or possibility of excessive stress. Pressing OK on these messages allows you to see the Analysis screen and you can accept the results as shown, or press the Review Input button to make changes on the input screen and then press Calculate again. You can repeat this interactive procedure as many times as required to obtain a satisfactory result.

Garter Spring Design

Quick and Easy Spring Design
with the QUICK SPRING DESIGNER

Garter Spring Design and Analysis

Common features are listed at the bottom of the Home Page The garter spring is essentially a helical extension spring formed into a circular ring with the ends firmly connected and usually statically loaded on its inside diameter. The program assumes an endless spring, ignoring the joining method which does not significantly affect the results. Initially, the input boxes for the free inside diameter and the spring coil diameter are not visible. When a value for the expanded inside diameter is entered, the missing boxes appear with suggested values entered. These can be edited if desired. Additional inputs are the radial load per unit of circumference and a choice from a drop-down list of 13 materials. An experience factor can be applied to the allowable stress. On pressing the Calculate button on the Design form,messages pop up (with suggestions for correction) if the spring index is high or low, or if allowable stresses can be exceeded under certain conditions. After viewing the calculated properties, you can go back to edit your input values, if necessary, by pressing the Review Input button.

Garter Spring Design

Data entry on the Garter Spring Analyst form is similar to that on the design form. In this case, required values are the free and expanded inside diameters of the spring and the coil mean diameter and the wire diameter. If the initial tension is not known, the program calculates a suitable value and inserts it in the data input box. Pressing Calculate on the Garter Analysis form will bring up, if applicable, messages to advise of the potential for exceeding stress limits, or high, or low spring index and they will include suggestions for correction. If you want to make changes, pressing the Review Input button will return you to the previous screen to edit the input, or you can accept the results as displayed.

Conical Disc (Belleville) Spring Design

Quick and Easy Spring Design
with the QUICK SPRING DESIGNER

Conical Disc Spring Design and Analysis

Common features are listed at the bottom of the Home Page The Design program for Conical Disc (Belleville) Springs will produce a set of spring dimensions that may be used as is, or used as a starter set to be refined in the Spring Analyzer. You can design springs with a linear characteristic or a regressive one that provides a close-to-constant load over wide ranges of deflection in the last 50 percent of deflection to flat. The program will calculate the number of springs required for large deflections to produce economic designs. The removal of set can result in appreciable increases in permissible stress levels and experienced users can enter an experience factor to take this into consideration. As is standard with all the input forms you cannot proceed without attending to any missing, or illogical entries. Then pressing the Calculate button brings up the output screen showing the input data and calculated values for a proposed design. Suitable inside and outside diameters, thickness and a dished height to suit the spring characteristics are shown. Also the number of springs in series required to achieve the specified deflection is given together with the free height and the important stress values. You can make changes by pressing the Review Input button and this takes you back to the Design input form. After pressing Calculate again you are returned to the output form. The interaction between the forms means that you can very quickly assess the results of changing the input factors.

Conical Disc (Belleville) Spring Design

When you press the Spring Analyzer button on the Conical Disc Design form this screen appears for input of data pertaining to an existing spring or spring design The form can be used to refine data developed on the spring design form. Data required for input include the inside and outside diameters, the material thickness, the dished height and a maximum deflection. You can also input an initial deflection if relevant to your study. Pressing Calculate on the Conical Disk Spring Analyzer form, assuming all required inputs are present, brings up the results screen. The input values are all displayed and if you have entered specific deflections of interest, these are reported with their properties at the top of the table of calculated properties. Below, properties for deflections of 25, 50, 75 and 100 percent of deflection to flat are listed. A curve of the spring's load/deflection characteristics can be plotted from these values.

with the QUICK SPRING DESIGNER

Helical Torsion Spring Design and Analysis

Common features are listed at the bottom of the Home Page Helical Torsion Springs can be designed for static or variable loads with the applicable text boxes becoming available for data input. For steady loads, one moment and a corresponding rotation are entered. For variable loads, two moments and the angle between them are entered — also a required life. Restrictions on coil diameter and a clearance between coils are optional inputs. Pressing the Calculate button before all the required input values are entered will bring a message, or messages, requesting the missing information. When the Calculate button on the Helical Torsion Spring Design form is pressed, if the spring index is high or low, or there is a chance of excessive stress, an information message or messages will appear and if it is thought necessary to edit the input, pressing the Review Input will return you to the Design data input screen. The instant interactive response between the two screens helps you to rapidly arrive at a satisfactory design.

Helical Torsion Spring Design

If the Spring Analyzer button on the Helical Torsion Spring Design form is pressed, a new form, similar in layout but designed to accept the properties of an existing spring or spring design appears. Data entry consists of the spring mean diameter, the wire diameter, the free length and the number of active coils. Either a value for rotation, or a moment must be entered for steady loads and for variable loads a ratio between load positions must be entered. Again, pressing the Calculate button before all the required input values are entered will bring a message, or messages, requesting the missing information. When the Calculate button on the Helical Torsion Spring Analysis form is pressed, if the spring index is high or low, or there is a chance of excessive stress, an information message or messages will appear and if it is thought necessary to edit the input, pressing the Review Input will return you to the Analysis data input screen. The instant interactive response between the two screens helps you to rapidly arrive at a satisfactory design.

Torsion Bar Design

Quick and Easy Spring Design
with the QUICK SPRING DESIGNER

Torsion Bar Analysis

Common features are listed at the bottom of the Home Page The Torsion Bar is one of the two types of spring that have no "Design from Scratch" option. Most applications are relatively simple so that a trial and error approach is adequate. The program will check the torsional performance of drawn circular wire, solid round bar, hollow round bar, solid rectangular bar and hollow rectangle bar. After selection of the section, only the inlet boxes applicable to that section are visible. Similarly, one or the other material drop-down lists are available, one for wire materials and the other for mechanical and structural steels. An experience factor can be applied to allowable stresses. Pressing the Calculate button on the Analysis data input form produces the screen on the right to report the input values and the calculated properties. The interactive nature of the analysis input screen and the corresponding output screen makes it very easy to test the effects of dimensional and/or material changes on the predicted properties.

Power and Clock Spring Design

Quick and Easy Spring Design
with the QUICK SPRING DESIGNER

Clock/Power Spring Design and Analysis

Common features are listed at the bottom of the Home Page Power springs, including clock and motor types are made from a strip of tempered steel or suitable alloy, attached to and wound around an arbor and confined in a case or drum. This program produces reliable designs for springs with total turns up to 30, and beyond that, it can be used to produce results that may be used as a guide for finalizing a design in the Spring Analyzer. The input data includes the maximum torque, total turns, material width and, optionally a percentage of turns for reporting characteristics at a specific number of rotations. The ratio of arbor diameter to material is set to a default value of 20 and this can be edited Pressing the Calculate button on the Power Spring Design form produces the output screen. Values calculated by the program and reported here include the spring material thickness and effective length, the case inside diameter, the arbor diameter, the ratio of length to thickness and the maximum stress. The number of turns, the torque and the stress are tabulated for 20, 40, 60, 80 and 100 percent of the total turns. The equivalent values for a selected percentage of total turns is also reported.

Constant Force Extension Spring Design

Quick and Easy Spring Design
with the QUICK SPRING DESIGNER

Constant Force Extension Spring Design and Analysis

Common features are listed at the bottom of the Home Page Both the Design and Analysis functions for Constant Force Extension springs are performed by the same form and option buttons are provided for selection of the required mode. Only the relevent text boxes are available for either mode. In the design mode, a default aspect ratio (material width/thickness) of 100 is already entered and it can be edited. Other inputs are the required extension, the rated load and the selected material The calculated properties include the material width and thickness, spool diameter, natural coil inside diameter, number of coils and other associated properties. A stress factor is reported and its relationship to the anticipated life of the spring is noted.

http://www.springwizard.com/conforce.htm (1 of 2) [09/Ago/2007 18:22:55]

Constant Force Extension Spring Design

On clicking the Analyze option on the Constant Force Extension Spring Design/Analysis form the text boxes are set to that mode. The input includes the spool diameter, the natural inside diameter of the coil, the material width and thickness and either the maximum extension or the total number of active coils. If the coil natural ID is unknown, the text box for it can be left blank and the program will calculate a preferred diameter and enter itin the box. The Analysis results screen shows the input values with the spring dimensions and the calculated properties inluding the initial extension (before the spring reaches the rated force), the estimated total material length, the loads at minimum and full extension, the maximum effective extension or the total number of active coils (depending on the data entered) and the outside diameter when the coils are fully retracted.

Constant Torque Spring Motor Design

Quick and Easy Spring Design
with the QUICK SPRING DESIGNER

Constant Torque Spring Motor Design and Analysis

Common features are listed at the bottom of the Home Page Constant torque spring motors adapt the principle of the constant force spring by attaching the free end of the spring to another larger drum and winding it around that drum in either the same or the reverse direction to that on the storage drum. The program uses the latter arrangement to produce higher torque and smoother operation. When the output drum is wound up and then released, the storage drum will rotate to retract the spring, thereby rotating the output drum. As the tension in the spring is virtually constant and the radius of the active coil on the output drum varies only slightly, a relatively constant torque is available at the output drum shaft. The data input form is used for either design or analysis by appropriate selection of mode. Only the relevant text boxes will be available in either case. In the design mode, the inputs include the aspect ratio (width/thickness) of the material, the output torque, a material selection and the total number of revolutions The result screen for Constant Torque Spring Motor design reproduces the input data values and the proposed spring dimensions. The calculated properties include the material width and thickness, the storage and output drum diameters, the natural coil inside diameter, the minimum center distance and the active and total material lengths.

Constant Torque Spring Motor Design

When the Analysis button is clicked the text boxes switch to that mode and the form can be used for calculation of the properties of an existing spring or spring design. Input values include the storage and output drum diameters, the natural inside coil diameter (if not known, a value will be assigned), the material width and thickness, the active material length and a material selection. The Constant Torque Analysis Results screen records the input values and the calculated properties including the rated torque, the number of revolutions, the minimum center distance and total material length, and stress considerations.
