Abstract

Abstract: Contact, impact and friction may induce none-smooth behaviors on velocity level for multi-rigid-body system. Variable structural dynamics can deal with them by loading and uploading constraints on the system. Variable structural dynamics for two dimensional dynamic system including contact, impact and friction is introduced. A 2D rod is presented to achieve the final dynamic simulation.

Key words: variable structure, contact, impact, friction

摘要： 通过约束加载和卸载的变结构方法来处理由接触、碰撞和摩擦导致多刚体系统在速度水平的非光滑动力学问题, 并从接触、碰撞和摩擦等方面介绍二维问题的变结构方法,最后提供了二维细杆在粗糙水平面上运动的动力学算例。

关键词: 变结构, 接触, 碰撞, 摩擦
