摘要

建立一种动态粘合算法,用于多体系统中刚体与弹性体或弹性体与弹性体接触问题的仿真。该算法通过装配矩阵和界面柔度矩阵构建接触界面粘合矩阵,用来传递接触力和位移,当接触位置改变时界面柔度矩阵和装配矩阵随之变化,粘合矩阵需要动态更新。利用该方法可以将刚柔耦合系统中相互接触的结构分成独立的子系统,分别在独立的程序或平台中进行分布式仿真。本文使用该方法进行刚体与弹性体接触仿真,和统一方程的刚柔耦合仿真结果基本一致。

Abstract

A new dynamic gluing algorithm that can be used to solve rigid-flexible and flexible-flexible contact problems of multibody system was established. Assemble matrix and interface flexibility matrix construct the gluing matrix, which is used to exchange contact force and displacement of contact pairs. Assemble matrix and interface flexibility matrix will change due to contact position changing, gluing matrix need to update every time step. Using this algorithm, two contacted structure of rigid-flexible coupling system can be decomposed into independent subsystems, which can be simulated in independent program or software. Dynamic gluing algorithm was used to simulate rigid and flexible body contact and the results are almost same as coupling simulation results with unified equation.
