| 摘 要： | 该文在多刚体系统离散时间传递矩阵法的基础上，建立了用于解决刚柔多体系统动力学问题的刚柔多体系统动力学离散时间传递矩阵法。通过该方法和其它方法的数值算例结果对比证明了该方法的有效性。与通常多体系统动力学方法相比，该方法涉及矩阵阶次低，无需总体系统动力学方程。该方法为解决一般刚柔多体系统动力学问题提供了强有力的新手段。

| Abstract: | Based on the discrete time transfer matrix method for multibody system dynamics ( MS-DT-TMM ) , a discrete time transfer matrix method for rigid-flexible multibody system dynamics is established. This method can be used to deal with the problem of rigid-flexible multibody system dynamics. Formulations of the method as well as the numerical example to validate the method are given. Compared with the conventional multibody dynamics methods, the order of matrices involved in the method is lower, and the overall dynamical equations of the multibody system is not needed. This method provides a powerful tool for general rigid-flexible multibody system dynamics. |
