摘　　要：以某高速摆动工况下应用的微型制冷机连杆轴承为研究对象,对其进行受力分析,计算轴承的接触变形、载荷分布、摩擦力矩,并基于ABAQUS建立高速摆动工况下连杆-轴承摆动系统温度场模型,分析径向载荷、摆动频率及摆动角度对轴承最高温度的影响,结果表明:随径向载荷、摆动频率、摆动角度增大,轴承最高温度增大,与摆动系统试验台验证结果一致,说明了仿真模型的正确性。Taking connecting rod bearing in miniature refrigerator under high speed oscillation as the research object,the loads of the bearing are analyzed,the contact deformation,load distribution and friction torque of the bearing are calculated,and the temperature field model of rod-bearing oscillating system under high-speed oscillating condition is established based on ABAQUS.The effects of radial load,oscillating frequency and oscillating amplitude on maximum temperature of the bearing are analyzed.The results show that with the increase of radial load,oscillating frequency,oscillating amplitude,the maximum temperature of the bearing increases,which is consistent with verification results obtained by oscillating tester,indicating the correctness of simulation model.
