Abstract: The dynamic transfer equations of a FBRE system excited by an off-center force are deduced according to the mechanical impedance method in this paper. The system is composed of a machine, isolators and flexible plate-like foundation. Power flow transmitted to the foundation is used as the object 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 active control is discussed.
Keywords: flexible foundation, off-center force, power flow, active control.
