摘要
利用机械阻抗方法推导了偏心力作用下 ,机器—隔振器—柔性板基础所组成的FBRE隔振系统的动态传递方程。以传递到柔性板基础的功率流为目标函数 ,通过计算机仿真计算 ,研究了在对称系统中偏心力作用下的功率流特性 ,分析了和对称力、力矩作用效果的不同和联系 。
The dynamic transfer equations of a FBRE system excite d by an off-center force are deduced according to the mechanical impedance metho d in this paper. The system is composed of a machine, isolators and flexible pla te-like foundation. Power flow transmitted to the foundation is used as the ob ject function. The characteristics of power flow of the symmetrical FBRE system, which is excited by an off-center force, are studied by computer simulation. The difference and the relation of the effects between the off-center force and the symmetrical force, as well as the moment are analyzed. The effect of the ac tive control is discussed.
