摘要

摘要: 根据柔性基础结构振动声辐射的控制需求，提出了柔性基础上应用金属橡胶隔振器的被动隔振方法。运用 ADAMS软件与有限元软件结合，仿真了基础材料、隔振器一次线性刚度、三次非线性刚度、粘性阻尼等参数改变时隔振系统的频域特性，得到了设备与基础的幅频响应曲线和系统的振级落差曲线，通过结果曲线的对比，分析了不同参数对系统隔振性能的影响，并提出了提高隔振效果、优化系统参数的一般方法。

Abstract: According to the requirement on controlling the structure acoustic radiation of the flexible base, a passive vibration isolation method which use metal rubber isolators is proposed in this paper. To analyze the dynamic performance of the metal rubber vibration isolation system on the flexible base, the ADAMS software is used together with a finite element analysis software. The dynamic frequency characteristics of the system on different materials of the flexible base, different linear stiffness, cubic nonlinear stiffness and damping of the isolator are obtained by numerical simulation using these two softwares, and the differences of vibration level with different parameters are calculated. Then the influences of these parameters on the vibration isolation performance are analyzed by comparing these results, and the method to improve the effect of vibration isolation and optimize the parameters of the system is presented.
