Study on SMA Pseudo-Rubber Metal Damper

Abstract:

In this paper, Shape Memory Alloy (SMA) Pseudo-Rubber Metal (PRM) was studied, and comparative test with common Pseudo-Rubber Metal was carried out. The enveloped area of hysteresis curve of SMA PRM is clearly larger than that of common PRM, which indicates the damping of SMA PRM overmatches that of common PRM. The stiffness value of SMA PRM and common PRM increases with their distortion amplitude’s increase, and the stiffness value of SMA PRM is less than that of common PRM. The carrying capacity, stiffness and damping of PRM are related with its relative density. The hysteresis behavior of SMA PRM is stable and basically not related with repeating load effect. Moreover, SMA PRM damper device was studied and developed, and comparative test with common Pseudo-Rubber Metal was carried out.
