摘　　要：以复杂机械系统动力学建模为研究背景,在计算多体动力学和多体系统离散时间传递矩阵法的理论基础上,论述了这两种方法动力学建模与分析的特点;在此基础上,提出了在计算多体动力学中混合多体系统离散时间传递矩阵法的算法,并论述了使用该算法对机械系统进行动力学建模及分析的过程。该算法适合于对复杂机械系统进行动力学建模及分析,并且易于使用计算机应用软件实现。以某典型机械连接结构为算例,通过该算法进行建模与分析,论证了该算法的可行性,也表明该算法的优点。Taking the dynamics modeling of complex system as research background, the computational dynamics of multi-body systems as well as the discrete time transfer matrix method were introduced and the advantages and disadvantages of the two methods were discussed. On this basis, a hybrid algorithm linking the dynamics of multibody system with the discrete time transfer matrix method was proposed. The dynamics modeling process for mechanical system using this hybrid algorithm was provided and a typical mechanical structure was taken as an illustrating example. The hybrid algorithm is fit for dynamics modeling and solving of complex mechanical systems, and it is easily achieved by computer application softwares. The results show the feasibility and features of the hybrid algorithm.
