| Abstract: | 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. |
