%X 针对大多数含间隙铰接副的磨损计算都非常复杂,精度和效率不能兼得,且很少能够与含间隙铰接副系统的动力学分析动态结合起来考虑表面接触刚度对磨损影响的问题,提出了一种新的含间隙铰接副磨损分析方法。基于无质量杆？驳？簧阻尼模型建立考虑接触刚度影响的含间隙铰接副系统动力学分析模型,利用非对称Winkler弹性基础模型计算接触压力分布,？用Archard磨损理论计算接触表面磨损量,对接触表面轮廓实时更新得出含间隙铰接副的动态磨损量。分析结果表明,在表面接触刚度较小时含间隙铰接副的动态磨损严重,且随系统转速的变化呈现出不同的变化趋势,反映了不同接触刚度下含间隙铰接副的动态磨损趋势。该方法计算精度和计算效率较高且充分考虑了表面接触刚度对含间隙铰接副动态磨损的影响,对含间隙铰接副系统的设计和动力学分析及磨损预测具有一定的指导意义。<br>Most of wear calculations for clearance joint are very complicated and the accuracy and efficiency can not be satisfied simultaneously, and the dynamic wear analysis rarely combines with the dynamics analysis of clearance joint system considering the effect of different surface contact stiffness. A dynamic wear analysis for joint clearance considering different contact stiffness is proposed. The mass？？less？？link and spring？？damping model is adopted to conduct dynamics analysis of clearance joint system considering different contact stiffness. The nonsymmetric Winkler surface model is taken to evaluate the contact pressure distribution, and the Archard wear theory is employed to calculate the worn mass of contact surface. The surface profile renews at real time with the wear calculation result, then the dynamic wear prediction of clearance joint is acquired. The dynamic wear trend for different contact stiffness is discussed. The proposed strategy fully considers the effects of contact stiffness on the dynamic wear of clearance joint, and reflects the dynamic wear trend of clearance joint surface for different contact stiffness with higher accuracy and efficiency
