The latest CAD package from Institute of Spring Technology enables the user to design compression springs by user specified geometry input.
The latest CAD package from Institute of Spring Technology enables the user to design compression springs with variability in wire diameter, outside diameter and pitch by user specified geometry input.
The software has successfully been used by the institute and has predicted the location of maximum stress at the position of failure in an automotive suspension spring with completely variable geometry.
The base module (validation program) includes constant or variable geometry, accurate free length and solid length calculation and detailed geometry specification possible (up to 100 increments per coil).
Users can also purchase an additional graphics module, which includes a drawing package, unprestress/prestress levels on load versus length graphs and influence of user-specified tolerances, load versus maximum stress, load or length versus rate, stress distribution at working load, Goodman diagram for fatigue life prediction and the influence of user specified tolerances, and upper limit relaxation predications based on maximum stress.
Incorporated in this package are all the latest features including: international, European and national material specifications; multiple languages for display screens (English, French, German, Spanish, with other languages available on application); and a networked version as standard at no extra cost, as well as greater integration into Windows for transfer of screen data via the clipboard to produce reports and send e-mails, with increased user friendliness and a customisation program for defaults and material input.
IST's Version 7 range of software programs are available for Windows 95/98/NT/2000/XP and are written and developed by the Institute of Spring Technology (IST) to be fully interactive for the spring designer.
The institute also offers a training package on the design of nonstandard compression springs, which features this unique software package.
