摘　　要：综合考虑薄膜润滑条件下间隙变化和剪切稀化对润滑剂性能的双重影响,得到了润滑剂在剪切稀化下的等效粘度模型,由此推导出考虑剪切稀化时的广义Reynolds方程和能量方程,得到了温度场的分布规律和温度与各性能参数的关系。The effect of clearance of bearing and shear thinning on lubricant characteristic was analyzed synthetically under thin film lubrication. Equivalent viscosity model of lubricant at shear thinning considered was built, and general Reynolds equation and energy equation at shear thinning considered were obtained. The temperature distributing was known under thin film lubrication, and the relation of the temperature and bearing performance parameters was confirmed.
