摘　　要：针对传统橡胶易老化、失效等缺点,设计一种基于金属橡胶的电梯曳引机减振器结构,制备出3种不同密度的阻尼元件并对其展开静力学试验研究。通过控制单一变量的试验方法,重点研究密度、压缩变形量、预紧力等因素对元件力学性能的影响。试验结果发现:随着成型密度、压缩变形量、预紧力的不断增大,金属橡胶元件的耗能和刚度呈现不断增大的趋势,损耗因子则呈现不断减小的趋势。To overcome the shortcomings of traditional rubber like easily aging and failuring,a metal rubber-based elevator traction machine shock absorber structure was designed,and three damping elements with different densities were prepared,on which static experiments were carried out.By the test method of controlling a single variable,the influence of factors such as density,compressive deformation,and pre-tightening force on the mechanical properties of the components,is studied with emphasis.The test results show that with the continuous increase of molding density,compression deformation and pre-tightening force,the energy consumption and stiffness of metal rubber components show continuous increasing trend,while the loss factor assumes continuous decreasing trend.
