摘要： 用连续介质力学的方法，对一种典型的刚—柔耦合系统进行了柔体小变形下的模态分析计算。所得结果全面地表现出柔体系统动力学中柔体模态的耦合特征。这些结果可以在柔体系统动力学离散近似方法研究中作为计算精度比对的参考。

Abstract: This paper deals with modal analysis of the flexible appendage of a typical rigid flexible coupling system based on the method of continuum mechanics.The analytical and numerical results presented in the paper represent more comprehensive coupling characteristics for the small deformation modes of the flexible appendage and can be taken for a reference for comparing the computational accuracy with that of the various approximative methods using the discretization of the flexible elements of the flexible multibody system .
