本篇文章尝试整理abaqus当中的kinematic coupling 和coupling 单元的区别: 一、Kinematic kinematic coupling: 约束一组节点的所有的或者指定的自由度到参考点的刚体运动中; 这个选项一般是用来在一个或者一组节点的的自由度和参考点的刚体运动之间施加约束。更好的提供这种类型的 运动约束的方式可以通过*coupling...
二、coupling *coupling:基于面的耦合约束 这个命令是用来在一个参考点和一组在面上的节点施加运动耦合或者分布耦合,它一定要和kinematic或者distributing命令一起使用; (按上面提到的其实couplingkinematic与kinematiccoupling是一样的,即都相当于nastran里面的RB2单元,但ABAQUS更建议使用couplingkinematic单元) 注意inp文本的...

It seems that you defined orientation for coupling constraint using offset to nodes method (coordinate system created by giving local node numbers for points a, b, and c). It's not allowed in Abaqus. Upvote 0 Downvote Apr 19, 2020 Thread starter #3 DavGray Mechanical Apr 9, 2020 8 ...
