摘要
提出一种求解多体系统动力学方程的迭代法，将多体系统分割成一个主子系统和一个或多个辅子系统，各子系统通过分割点的位移、速度、加速度和力的协调相联系，从而大大降低了方程的耦合程度、非线性和刚性。文中详细讨论了迭代法的收敛条件。
In this paper, an iteration method used for solving dynamic equations of multibody system is presented. According to the method, a multibody system is divided into one main subsystem and one or several subsystems. The coordinate conditions of displacement、 speed、 acceleration and force in division section relate the subsystems, so the coupling degree, non linearity and stiffness of the dynamic equations are debated greatly. The convergence condition of iteration method is discussed in detail.
