摘　　要：从微观上研究金属橡胶的微元刚度,从宏观上分析金属橡胶的迟滞回线特性;制备多组规格不同的金属橡胶试件并加以组合匹配获得组合型金属橡胶试件,并对其进行准静态加卸载试验,得到金属橡胶的刚度曲线及平均刚度,指出组合型金属橡胶的优势,分析金属丝直径和金属橡胶相对密度对金属橡胶组合刚度的影响。最后基于金属橡胶悬臂梁杆系接触作用模型,运用ANSYS workbench有限元分析软件对单个及组合型金属橡胶进行仿真分析,仿真结果与试验结果基本一致。The micro-stiffness of the metallic rubber is studied microscopically,and the hysteresis loop characteristics of the metallic rubber are analyzed macroscopically.Several groups of different specifications of the metallic rubber are prepared to obtain the composite metallic rubber specimens and the quasi-static loading and unloading tests are carried out for them.The shrinkage curves and the average stiffness of the metallic rubber composites are obtained.The advantage of the composite metal rubber is pointed out.The influences of the diameter of the metallic wire and the density of the metallic rubber composite on the stiffness are analyzed.Finally,a cantilever beam model of the metallic rubber is established and simulated by means of the ANSYS workbench software.The simulation results are basically identical to the testing results.
