摘要
工程实际中的活动铰连接均存在微小间隙和接触变形,利用接触变形建模方法能求出铰中的接触碰撞力。本文全面总结了地面和航天机构中现有的含间隙铰接触变形模型、数值积分方法、铰参数辨识以及系统动态特性实验方法,指出了当前含间隙多柔体系统动力学研究中存在的问题及今后的研究方向。
Small clearances and micro deformationsunavoidably exist in active joint connections in practicalengineering. The impact forces in these joints can beobtained by modeling the contact deformation-forcesrelations. This paper summarized comprehensively theexisting contact deformation models, numericalsimulation schemes, parameters identification methodsand experimental studies on dynamics of ground andspace mechanisms with joint clearances. Finallyproblems in present researches are pointed out and someaspects for future developments suggested.
