An generalized inverse subsructuring method was develped for multi-component coupled system, the back-caculating formula for four-component coupled system was obtained as an example. Then, the mothod was verified by a lumped parameter model, the FRFs of the components and coupling stiffness were predicted by the system-level FRFs applying the developed method and compared with the given value, showing perfect agreement. The results indicated that the propsed method is effective to model the multi-component coupled system.
