隔振器布置方式对隔振性能影响研究

Research on Influence of Vibration Isolator Arrangement on Vibration Isolation Performance

摘要: 隔振器布置对隔振体系位姿、稳定性及隔振效果等具有重要影响。本文对四种典型的隔振器布置方式的隔振性能进行了研究，结果表明五点支撑式相比三点支撑式、四点支撑式和六点支撑式更加合理，而常用的四点支撑式及六点支撑式并非理想体系。基于质刚重合的解耦策略可以有效降低自由度耦合带来的体系不利影响。本研究对于隔振体系优化设计具有一定的启示，对实际工程亦有指导作用。

Abstract: The vibration isolator arrangement has an important influence on the posture, stability and vibration isolation effect of the vibration isolation system. In this paper, the vibration isolation performance of four typical vibration isolator arrangements were studied, and the results showed that the five-point support is more reasonable than the three-point support, four-point support and six-point support, and the usually used four-point and six-point support were proved not the most ideal way. In final, the decoupling strategy based on the coincidence of mass and stiffness was performed out, by which the adverse effects of the system caused by the coupling of degrees of freedom could be effectively eliminated. This study has certain implications for the optimal design of the vibration isolation system, and it also plays a guiding role in the actual engineering.
