摘要

为了在开展含间隙铰多体系统动力学性能分析时选择最佳的接触力计算方法，以含间隙铰曲柄滑块机构为对象，建立了含间隙铰曲柄滑块机构多体动力学模型，针对几种接触力计算方法进行系统的对比分析。研究了不同间隙、曲柄转速和恢复系数下，接触力计算方法对曲柄滑块机构动力学性能分析的影响。结果表明，在研究径向间隙、驱动载荷和恢复系数变化对多体系统动力学影响时，选择Lankarani-Nikravesh接触力模型和Zhiying-Qishao接触力模型都相对可靠，且Zhiying-Qishao接触力模型对恢复系数敏感程度最低。

Abstract

In order to select the best contact force calculation method for the dynamics performance analysis of multibody systems involving joints with clearance， a dynamics model of a crank slider mechanism involving joints with clearance is established and a systematic comparative analysis is performed for calculation methods of contact force with the crank slider mechanism involving joints with clearance as the object. The influence of the calculation method of contact force on dynamics performance analysis of the crank slider mechanism under different clearances， crank speeds and recovery factors is studied. The analysis results show that when studying the influences of changes in radial clearance， driving load， and recovery coefficient on dynamics of multibody systems， both the Lankarani-Nikravesh contact force model and the ZhiYing-QiShao contact force model are relatively reliable， and the ZhiYing-QiShao contact force model is the least sensitive to the recovery coefficient.
