Abstract

Taking the modeling of complex system dynamics as research background, with the instruction of computational dynamics of multi-body systems theory and discrete time transfer matrix method, this paper discusses the advantages and disadvantages of the two methods about modeling and solving. On that basis, the hybrid algorithm of dynamics of multibody system introduced discrete time transfer matrix method is proposed. And, this paper discusses the dynamics modeling process of mechanical system using this hybrid algorithm. The hybrid algorithm is fit for dynamics modeling and solving of complex mechanical system, and it is easily achieved by computer application softwares. Taken the typical mechanical structure as example, the whole process of modeling and solving by hybrid algorithm is achieved. The results show the feasibility and characteristics of the hybrid algorithm.
