摘　　要：针对往复机械连杆大端轴承典型的磨损故障进行仿真与实验研究,探究磨损对连杆大端轴承润滑各参数的影响。以Reynolds方程为基础,通过模拟不同情况的轴承磨损:不同磨损宽度、不同磨损深度、不同磨损位置,全面分析磨损程度与轴承润滑参数,特别是轴承温度之间的对应关联。通过在实验台机组连杆轴承上安装温度传感器,对连杆温度进行在线监测,实验验证了磨损状态下轴承温度的变化规律。In this paper,simulation and experimental studies of typical wear fault of the reciprocating machinery connecting rod big end bearing,explore the influence of the wear and tear on the lubrication parameters of the connecting rod big end bearing. Based on the Reynolds equation,by simulating different bearing wear situations： different widths,different depths and different positions, a comprehensive analysis of the associations between the degrees of wear of bearing and lubrication parameters,in particular the bearing temperatures. By installing the temperature sensor in the test unit connecting rod bearings,connecting rod temperature is on-line monitored,and the variation rules of temperature of the bearing under the state of wear are experimental confirmed.
