摘要
用完全笛卡尔坐标描述多体系统的运动学和动力学在提高计算效率方面有突出优点。导出用完全笛卡尔坐标表示的刚体及多体系统运动学和动力学模型，研制了相应的通用仿真软件ＤＡＭＳ。通过ＤＡＭＳ软件对算例进行的动力学分析与计算，表明该方法及软件的有效性。
The formulation of kinematics and dynamics of multibody system based on the fully Cartesian coordinates has an important advantagement in computational efficiency. The model of kinematics and dynamics in fullly Cartesian coordinates is given, and its current simulation software DAMS os developed. It has shown the effectiveness of this approach and software by using software DAMS to analyze and calculate the dgnamics of examples.
