摘　　要：作为一种多体系统动力学新方法,多体系统传递矩阵法由于其无需系统总体动力学方程和快速计算的特点,已被广泛用于各种多管火箭、自行火炮、舰炮等复杂大型机械系统动力学分析与设计.本文介绍了该方法的研究进展,包括:线性多体系统传递矩阵法、多体系统离散时间传递矩阵法、二维系统传递矩阵法、受控多体系统传递矩阵法、多体系统传递矩阵法和通常动力学方法的混合方法等,给出了该方法解决自行火炮、多管火箭武器多体系统动力学的重大工程应用实例.As a new method of multibody system dynamics, the transfer matrix method of multibody system has the following characteristics： without the global dynamics equation of system, low order of matrix involved, high efficiency. It has been widely used in the dynamic design of many complex mechanical systems, such as multiple launch rocket system, self-propelled artillery system, and warship gun system. In this paper, the advances in transfer matrix method of multibody system, including linear transfer matrix method of multibody system, discrete time transfer matrix method of multibody system, transfer matrix method of two-dimension system, transfer matrix method of controlled multibody system, and the mixed method of transfer matrix method of multibody system and ordinary dynamics methods, are presented. Some engineering applications of this method on self-propelled artillery system and multiple launch rocket system are also given.
