Pall-typedampers（PFD）具有良好的耗能性能，形状记忆合金（SMA）支撑具有良好的超弹性性能，因此提出PFD-SMA支撑体系。通过对PFD-SMA支座系统的试验研究，分析了Pall型摩擦阻尼器的预紧力、形状记忆合金支座的刚度和长度参数对其滞回特性的影响。试验结果表明，PFD-SMA支护体系具有良好的超弹性耗能和复位性能，随着预紧力的增大，其超弹性性能表现更好，滞回曲线也表现出超弹性性能，验证了有限元分析的正确性。
Pall-typed dampers(PFD) have good energy dissipation, and shape memory alloy(SMA) brace has good super-elastic performance, so the PFD-SMA support system is put forward. Through the test study of PFD-SMA support system, analyze the influence to its hysteretic characteristic by preload force of Pall-typed frictional damper, the stiffness and length parameters of shape memory alloy support. The test results show that PFD-SMA support system s have good energy dissipation and good reposition due to its super-elastic performance, with pre-load force increase, its super-elastic performance acts better, its hysteretic curve show super-elastic performance too, and it verifies the correctness of the finite element analysis.
