Extension Spring Design by Ray Tools app for iPhone and iPad

Historically spring design has always been a challenge. In a manufacturing environment the use of stock springs has always been the first approach. But then the design changes a little or the stock spring is not quite what is needed and the designer must resort to designing a spring modification or a spring from scratch. This program provides a simplified method to design extension springs or verifying stock spring offerings with slightly different parameters.

Features:
-Use as stand alone or to compare commercial springs.
-Calculates all spring parameters force, stress and deflection as you edit.
-Change inputs using adjustors or retro keyboard entry.
-Select from 12 Standard Materials or define Your Own.
-Warns for design errors and corrects for installed length less than free length.
-Complete Help, Glossary and design error definition screens.
-Save and retrieve user defined springs.
-Email result file and data to home computer to be opened in any spreadsheet or text-editing program. Includes an image of the design screen for printing.
-Warns for zero entries.
-English or Metric Units with forces in Pounds or Ounces and in Metric Newton’s or Grams.
-Left or right hand wound springs.
-Recommendations for electroplating and heat-treating with documentation references.


Note: As with all complicated computer programs the user is responsible for verification, application and use. This program is a guide to understanding that uses approximations to simulate compression springs.
