Extension Spring Design Calculator

Advanced Spring Design (ASD7) is a spring design calculator jointly developed by Universal Technical Systems and the Spring Manufacturers Institute (SMI). This helpful resource merges engineering expertise with customized calculations to aid manufacturers in quality extension spring design.
Extension springs are just one type of spring this tool serves. The ASD7 calculator also aids in the manufacture of compression springs, spiral forms, torsion springs, garter springs, snap rings, washers, beams, and torsion bars.

Developed in a completely graphical environment, Advanced Spring Design features convenient and automatic unit conversion as well as convenient access to dynamic plots and reports. The ASD7 also includes an expandable extension springs material database, a profile system for saving and incorporating frequently used input data sets, as well as exportable DXF extension springs drawings.

The ASD7 calculator allows users to enter specifications to find extension spring rates and loads. Extension springs designs can also be backsolved for any variable.

This extension spring calculator provides SMI acceptable tolerances and calculates maximum safe loads. It also warns against potential design flaws such as settling or buckling.

W.B. Jones is expert at using this technology to design Custom Extension Springs. Let us design one to meet your exact specifications.
