Spring and Spring Aids

This program provides machine control for cyclic tests designed to measure dynamic and static stiffness characteristics and endurance of springs, spring aids, bushes and rubber products and similar materials. Endurance tests can be carried out under either load or position control. Peak and trough loads as well as peak and trough positions are plotted in real time providing an early assessment of possible damage.

Stiffness tests can be initiated either automatically at regular intervals during an endurance test or at any time by the user. Static stiffness tests are carried out under constant ramp rate, monitoring load and displacement values, while dynamic stiffness tests utilise sinewave. Endurance and stiffness test results are stored for future reference, re-plotting and recalculation of dynamic and static stiffness coefficients and phase angles facilities are provided.
