Abstract:

The paper deals with dynamic response prediction of composite structures which consists of two linear components coupled by some nonlinear vibration isolators. Based on the measured impulse response functions of the linear substructures, three kinds of dynamic equations of interfacial integeration are proposed and a procdure to transfrom the dynamic equations of integeral type into a set of ordinary differential equations is suggested. Computer simulations and a real test are given to verify the effectiveness of the theoretical results.
