【摘要】 以数值仿真技术对曲柄滑块机构中的铰链摩擦副磨损状态进行了研究,建立了同时考虑压力和温度影响时铰链机构的磨损仿真模型,对3对铰链接触处的磨损提出了具体的算法方案,在VisualBasic环境下编写了通用程序获得了更加准确的仿真结果。首次提出了磨损概率寿命的概念,在载荷呈正态随机分布时利用蒙特卡洛法计算出3对铰链摩擦副的磨损概率寿命。更多还原

【Abstract】 Based on numerical simulation,a study was made on the wear state of hinge configurations in a crane-block mechanism.Simulation models were established in which load and temperature were taken into consideration.The wear algorithm was proposed for the three couples of hinge configurations,the program was coded using Visual Basic,and the simulation results obtained was more accurate than before.A concept of probabilistic wear lifetime was presented for the first time,which was resolved by Monte Calro method when the load is of normal distribution.更多还原
