Abstract

Abstract

After analyzing the simple cyclic loading test, a concept of loading test with random process is suggested. As for certain power spectrum and displacement, one stochastic process is simulated and used into servo- dynamic test system. On the other hand, the condition of varying power spectrum and displacement is also considered. For analyzing the result of random test, the methods of equivalent stiffness, equivalent damping coefficient based on statistics are prompted. The random testing method resolved the coupling between loading velocity and frequency, and also simplified the assorting of loading circumstance. M eanwhile, the random testing method achieved the dynamic test for instantaneous characteristic of the specimen. As for other specimen such as rubber isolator, this method also has an advantage of utilization.
