摘要
利用传递导纳矩阵法推导了偏心力作用下 ,机器 隔振器 柔性基础复杂系统的动态传递方程 ,以传递到基础的功率流为衡量指标 .通过功率谱分析 ,研究了偏心力作用下的功率流特性 。
The dynamic transfer equations of the complex system excited by an eccentric force are deduced according to the mechanical impedance method . The system is composed of a machine, isolators and flexible foundation. Power flow transmitted to the foundation is used as the object function. The characteristics of power flow are studied by analyzing the power flow spectra. The effects of the active control are discussed.
