摘　　要：研究了多个刚体和弹性体耦合系统的振动特性 ,构造了满足自共轭条件的耦合多体系统特征值问题的正交增广特征矢量 。The vibration characterictics of a coupled system made up of elastic bodies and rigid bodies is investigated.The orthogonal augmented eigenfunctions of eigenvalue problem and boundary problem of the system which is self adjoint, are developed. The general response of the system to arbitrary excitations is accurately represented by the augmented eigenfunction series.

关 键 词：刚体 弹性体 耦合系统 多体系统 振动性 响应
