摘要
针对多体结构中连接部位带来的运动不连续问题 ,提出了将连接部件不作节点处理而作单元看待的设想。从力学基本原理出发推导了单元的刚度矩阵与阻尼矩阵 。
A finite element model for the joints in multi body structures has been presented. Based on the mechanical principles, the stiffness matrix and damping matrix of the finite element of the joint have been deduced. By this way, the non continuous physical system becomes continuous mathematically. So, the idea presented in this paper gives us another way to analyze the dynamical problem in a multi body structures.
