| 摘 要： | 通过对金属橡胶材料进行振动特性试验,总结了不同激励水平、不同相对密度及不同材质对其振动特性的影响。在考虑非线性刚度和非线性阻尼的基础上,给出描述金属橡胶材料动态特性的方法,进行了稳态振动响应计算,并与试验结果进行了对比。结果表明:振动越大,金属橡胶材料的减振效果越好。

| Abstract: | Experiments were performed to study the effect of varies excitation level relative density and material properties on the vibration characteristics of Metal Rubber (MR).Some general disciplinarians of characteristics of MR were found.Based on non-rigidity and non-damping,the method of describing vibration performance of MR was presented,steady response was calculated,and the results were contrast to testing results.The results show that the large the vibration intensity,the better the damping effet will be. |
