摘要
简要地阐述多体系统动力学单向递推组集建模方法，介绍根据这种方法开发而成的仿真软件系统ＤＡＦＭＢ及它的功能与特点。通过双摆算例指出本文提出的模型在计算效率与计算精度方面优于笛卡尔坐标的微分－代数方程。
Based on the mixed coordinates, a forward recursive and combinative formulation, and its software implementation for dynamics of flexible multibody systems with any tree topology are presented in the paper. The functions of the software named DAFMB, are introduced in detail. A two pendulum example is studied to illustrate computational efficiency and stability by comparison with the formulation based on Cartesian coordinates, and DAFMB may be an efficient tool of computer aided analysis for dynamics and control of flexible multibody systems.
