摘要

A direct Multibody System Transfer Matrix Method (MSTMM) is developed to analyze the vibration characteristics and orthogonality of linear multibody systems. The method is applied to (1) solve the eigenvalue problem of linear multibody systems including rigid and flexible bodies, (2) obtain the general orthogonality of eigenvectors of the MBS, (3) get the accurate analysis of the dynamic response of the MBS, (4) find the connected parameters between bodies used in the computation of the MBS. In this paper, the eigenvalue and the orthogonality condition for general linear multibody systems are gained by developing the MSTMM. The vibration characteristics and the dynamic response of a multibody system including rigid and elastic bodies for practical engineering problems are simulated and tested. The results obtained by simulation and experiment have good agreement.
