多刚体系统力分析的一种算法

本文运用矩矢概念,将空间约束力统一用六维矢量表示,并借助于有限转动理论及旋量理论计算力的投影和力对轴的矩,从而得到了静定刚体系统力分析的既统一又简洁的分块矩阵单元分割法。这种算法能以较少的参数获得计算结果,同时提供了程式化的计算步骤。所以,适用于电算。本文提出的算法已由SXCF通用程序实施。

A Method of the Force Analysis for System of Rigid Bodies

In this paper, tne space constraint force is uniformly expressed as a six-dim-ensional vector according to the concept of the Moment Vector. With the helpof the theory of finite rotation and screw the projection of the force and mo-ment of the force about an axis is calculated, so a uniform and simple method ofelement division of partitioned matrix for the static analysis of the statically de-terminate system of rigid bodies is obtained. Such calculation indicates that theevaluation may be found with less parameters in a formulated operation. Conse-quently, this method is fairly appropriate for computers. A SXCF universal program has been made from the method described in thispaper.
