摘要
对柔性被动隔振系统的功率流传递特性进行研究,建立了隔振器倾斜放置的隔振系统的理论模型,运用机械导纳法推导了系统的功率流传递函数.数值仿真中,分别考虑了无限板和有限板、厚板和薄板的情况,通过大量的数值仿真对这些情况的功率流特性进行了详细研究,得到一些对工程实际具有借鉴意义的结论.
The characteristics of power transmission of vibration isolating system with passive mounts on a flexible plate foundation was studied. The theoretical model considering two inclined mounts was established, and the power transfer function of the system was deduced using the mechanical admittance method. In numerical simula- tions, infinite and finite plates with both thick and thin dimension were all taken into account. The characteristics of power transmission of the system was investigated through numerical simulations, and some conclusions that can benefit the practical engineering were obtained.
