Abstract

The shock protection characteristics of Metal Rubber isolator are studied theoretically and experimentally. Based on the primary loading line and the hysteresis loops of isolators, the calculation method of maximum response of nonlinear shock protection system with dry friction damping on the short and long shock impulses is proposed. The stepping integration of the maximum response is programmed by using Matlab software. The effects of the structural parameters, the load, and the shock acceleration level on the shock protection performance of metal rubber isolators are researched experimentally to testify the theoretical calculation method. The results are beneficial to the engineering application of metal rubber isolators.
