在对楼层安装机器柔性耦合动力系统功率流理论研究的基础上，本文进一步从实验观点研究了机器—基础柔性隔振系统的功率流传递谱。建立了柔性隔振系统实验模型和功率流测试分析系统，从能量观点对机器—隔振器—弹性基础耦合系统的振动传递机理进行了实验研究。通过对称和非对称系统的功率流对比实验，揭示了功率流传递谱的非对称效应，验证了理论分析的正确性。
Based on the theory of power flow in flexible coupling power system of floor-mounted machines, this paper further studies the power flow transfer spectrum of machine-base flexible vibration isolation system from the experimental point of view. The experimental model of flexible vibration isolation system and the power flow test and analysis system are established. The vibration transmission mechanism of the mechanical-vibration isolator-elastic foundation coupling system is experimentally studied from the energy point of view. By comparing the power flow of symmetrical and asymmetrical systems, the asymmetric effect of the power flow transmission spectrum is revealed, and the correctness of the theoretical analysis is verified.
