[摘要] 设置有阻尼器的土木工程结构，其抗震减震控制的效果与阻尼器的工作性能密切相关。基于普通粘滞阻尼器，利用形状记忆合金良好的超弹性性能和形状记忆特性，设计了新型自复位混合阻尼器。该阻尼器主要是利用形状记忆合金和普通粘滞阻尼器的协同耗能机制，在形状记忆合金材料力学性能试验的基础上，对其超弹性性能进行分析，然后分析了新型自复位混合阻尼器的工作原理及耗能机制；利用数值计算对不同规格的阻尼器进行分析，得到了不同阻尼器的位移幅值、加载频率等工况对SMA自复位混合阻尼器的单位循环耗能的影响效果。通过对比分析，得到了阻尼器参数的最佳组合，进而能够保，进而能够保证其发挥良好的耗能减震效果，为其工程应用奠定理论基础。

Abstract: The performance of the damper is directly related to civil engineering structure damping control quality. Based on the research of common viscous damper and utilization of Shape memory alloy (SMA) which has shape memory characteristic and super elastic properties, this text design a new kind of SMA then self-replacement hybrid damper. In consideration of all factors, using common viscous damper with SMA silk, achieve optimal energy effect. Firstly, the text make the SMA material mechanics performance experiment, analyze its super elastic properties and obtain material constitutive relation, then analyze working principle of the damper and working mechanism of the SMA and viscous damper which consume energy commonly. In different specifications of damper on different SMA, through the application of numerical calculation and simulation of MATLAB, this text analyze the condition of the damper displacement amplitude and loading frequency which influent on units cyclic consumption of SMA then self-replacement hybrid damper. Through the comparative analysis, the optimal combination of various parameters, so as to achieve the optimal energy effect, make this series of damper, so that people use more convenient.

Keywords: SMA damper; energy consumption; optimal combination
