Formulation of matrix assembly for self-driven modeling of constrained mechanical system

针对约束机械系统的运动方程组系数矩阵的组装 ,推导出适合于计算机自动建模所有矩阵组装公式 ,提出了分块贡献法 ,并将其转化为算法 。

Aiming at coefficient matrix assembling, this paper presented all matrix assembly formulas for computer automobile modeling. A method different block contribute promoting matrix assembly was put forward. A constrained mechanical system analysis prototype InteVPAS 1.0 was also developed based on the matrix assembly algorithm.
