Abstract:The indirect coupling loss factor between two flexible bodies indirect coupled through a rigid body was calculated from the energy conversation equation, in which the energy of each subsystems was accounted through the Finite Element Energy Flow model excited by the random wide-band excitation. The energy of each subsystem should be space and frequency averaged. Compared with the traditional Finite Element Method, the new procedure in this paper was efficient in computation time; and was reliable compared with the traditional SEA Model. Last, the method was verified though the experiment.
