摘要
针对振动隔离中基础的非刚性问题，通过理论推导和数值计算，得到有关柔性板基础上多点支承隔振系统的功率流传特性的若干重要结论，并以传递到基础的功率流频率平均响应为目标函数，以隔振器的刚度、阻尼以及机器的质量为约束条件进行了优化．提出了控制系统振动和结构噪声传播的有效途径．
The power flow transmission from a vibrating rigid machine through multiple elastic mounts to a flexible simply supported plate is investigated theoretically and numberically, some important conclusions are attained. The frequency average power trasmitted to the foundation is used as the cost function to be minimized, considering the stiffness and damping factor of the isolator and the mass of the machine. The control of vibration and noise of this system is discussed.
