Abstract
The dynamic transfer equations of FBRE system excited by an off-center force are deduced according to the mechanical impedance method in this paper. FBRE system is composed of a machine, isolators and a flexible plate-like foundation. The characteristics of power flow of FBRE system excited by an off-center force are studied with the power transmitted to the foundation as the objective function. The difference and relationship of the effects between the symmetrical force and moment, and an off-center force are analyzed. The active control effects are also discussed.
