摘　　要：[目的]为了研究某电动汽车减速器不同输入转速、润滑油液位及润滑油温度,对油液颗粒分布、齿轮搅拌油液时的功率损耗以及轴承润滑性能的影响,开展某电动汽车减速器内部腔体润滑效果的分析和齿轮搅油功率损失的相关研究。[方法]应用ShonDY软件中基于改进的半隐式运动粒子法(MPS)进行仿真分析,通过自带的后处理功能获取减速器内部流场数据,根据获得的数据来分析不同输入转速、润滑油液位及润滑油温度,对油液颗粒分布、齿轮搅拌油液时的功率损耗以及轴承润滑性能的影响。[结果]对仿真数据进行分析得出,不同输入转速、润滑油液位对油液颗粒分布、齿轮搅拌油液时的功率损耗以及轴承润滑性能有显著影响,润滑油温度对润滑效果、油液粒子分布和搅油功率损失的影响较小。[结论]研究结果可为电动汽车减速器内部腔体和齿轮的相关设计提供参考。[Purposes]In order to study the influence of an electric vehicle reducer at different input speed,lubricating oil level and lubricating oil temperature on the distribution of oil particles,the power loss of gear mixing oil,and the bearing lubrication performance,the analysis of the lubrication effect of the internal cavity of an electric vehicle reducer and the related study of gear stirring oil power loss are carried out.[Methods]In this paper,the simulation analysis is carried out based on the improved semi-implicit moving particle method(MPS)in ShonDY software.The data of the internal flow field of the re-ducer are obtained through the built-in post-processing function.According to the obtained data,the ef-fects of different input speeds,lubricating oil level and lubricating oil temperature on the distribution of oil particles,the power loss of stirring oil and the lubrication performance of the bearing are analyzed.[Findings]The analysis and study of the simulation data can show that different input speed and lubri-cating oil level have significant effects on the distribution of oil particles,the power loss of of stirring oil and the bearing lubrication performance,and the lubricating oil temperature has little influence on the lu-brication effect,oil particle distribution and the power loss of stirring oil.[Conclusions]The obtained re-sults will provide a reference for the design of the internal cavity and gear of an electric vehicle reducer.
