本文研究了机器上楼后所形成的复杂柔性耦合系统的振动功率流。从非对称多支承的工程实际出发，运用子系统导纳综合法，考虑了高频振动时基础结构的非刚性以及多支承间的动力耦合影响，分析了机器一隔振器一弹性基础复杂系统的动态特性，并与对称简化系统进行了比较，揭示了非对称性对系统功率流的影响规律，并提出了控制系统结构噪声的有效途径。
In this paper, we study the vibration power flow of complex flexible coupling system formed after the machine is upstairs. Based on the engineering practice of ASM, the subsystem admittance synthesis method is used. Considering the non-rigidity of the foundation structure under high-frequency vibration and the dynamic coupling effect between multiple supports, the analysis of a flexible foundation-based complex system Compared with symmetrical simplified system, the influence of asymmetry on system power flow is revealed, and an effective way to control system structure noise is proposed.
