Study of Dynamic Response of Stranded Wire Springs

Abstract

A total of 60 TD-recordings were made of 5 different test springs, 42 records in impact loading at velocities up to 560 inch/sec, and 18 records on the sudden release of spring, at extension velocities up to 830 inch/sec. Each record was evaluated with respect to surge time (both wave head and wave peak), velocities, minimum height reached, etc. For single wire springs, the formulas of the Surge Wave Theory were recapitulated and summarized and corresponding formulas were derived for stranded wire springs. These formulas use lumped values as parameters, such as the active weight of spring (or per coil) and the measured rate of the spring (or coil), instead of wire diameter d and mean coil diameter D.
