摘　　要：对高速圆柱滚子轴承在机械载荷和热载荷联合作用下的应力场进行研究,建立在列车实际服役工况下的轴承热力耦合模型。结果表明,考虑热力耦合效应以及轨道不平顺作用时,轴承温度场以及应力场均存在较明显的差异,且该差异受到高速列车振动环境的影响。Studied the stress field of high-speed cylindrical roller bearing under the combined action of mechanical load and thermal load,and established the bearing thermal-mechanical coupling model under the actual service condition of the train.The results show that the temperature field and stress field of bearings are obviously different when considering the thermal-mechanical coupling effect and the action of track irregularity,and the difference is affected by the vibration environment of high-speed trains.
