【摘要】 本文结合数值积分法，将不适合于时变、非线性系统的经典传递矩阵法推广到非线性多体系统动力学，形成了多体系统离散时间传递矩阵法的基本理论。并将其成功应用于刚弹耦合舰炮多体系统发射动力学计算。 与其它多体系统动力学方法相比，多体系统离散时间传递矩阵法具有如下特点：1 无需建立总体系统动力学方程，因而应用和计算方便。2 可事先建立各种元件的传递矩阵库，并象拼积木一样根据实际多体系统结构用元件的传递矩阵拼装得到系统的传递矩阵，方便而灵活地计算多体系统的动力学特性。3 能综合分析计算线性时不变、时变、非线性多体系统动力学问题。更多还原

【Abstract】 By combining the numerical integral method, the conventional transfer matrix method that can not be applied in the time varying or nonlinear problems is expanded into the nonlinear multibody system dynamics in this paper. The basic theory of discrete time transfer matrix method (DT-TMM) of multibody system is proposed primarily. And this method is applied successfully in the launch dynamics of the shipboard gun multibody system including rigid body and elastic body.In contrast with other conventional multibody system dynamics method, DT-TMM has following characteristics: 1. The overall dynamic equations for a multibody system are not necessary to establish, and the application and computing are done conveniently. 2. The transfer matrix library of multifarious elements can be established in advance. According to the structure of the multibody system, the overall system transfer matrix can be got like fitting the building block. The dynamic characteristics of the multibody system can be gotten easily and conveniently. 3. DT-TMM can be applied in the linear time invariant, time varying or nonlinear multibody system dynamic problems.更多还原
