In this paper we present the effect of vibration source on the power flow transmission in a compound flexible system. Considering the internal impedance of the source, a general model is here proposed, and the generalized transfer equations of the system and the closed form solutions for power flow in the fiexible system are then developed, with which the effects of the source characteristics on power flow transmission are discussed. The investigation shows that when the source and receiver impedances are comparable, substantial error can occur in the power flow estimation if the source is assumed to be an ideal constant force source (CFS)or a constant velocity source (CVS).
