摘　　要：本文以矩形橡胶密封圈和矩形密封槽的匹配设计作为研究对象,根据压缩率和填充率的范围要求,对矩形橡胶密封圈和密封槽尺寸进行匹配设计。同时,对于该密封系统在新能源汽车驱动电机环境的实际应用,在不同的环境温度时,对于不同的尺寸匹配结果,基于Ansys软件进行了热仿真,根据仿真结果发现,当环境温度在-40℃~160℃区间变化时,不同尺寸匹配情况下的压缩率和填充率都是随环境温度的升高而升高,但是依然满足密封系统的压缩率和填充率的范围要求。文章提出的根据压缩率和填充率范围要求,在温度变化的环境下,对矩形橡胶密封圈和矩形密封槽进行匹配设计,具有一定的工程指导意义。In this paper,the matching design of rectangular rubber sealing ring and rectangular sealing groove is taken as the research object,and the matching design of rectangular rubber sealing ring and sealing groove size is carried out according to the range requirements of compression ratio and filling rate.At the same time,for the practical application of the sealing system in the new energy vehicle drive motor environment,at different ambient temperatures,for different size matching results,thermal simulation is carried out based on Ansys software,according to the simulation results.It is found that when the ambient temperature changes in the range of-40°C~160°C,the compression ratio and filling rate under different size matching conditions are increased with the increase of ambient temperature,but still meet the range requirements of the compression rate and filling rate of the sealing system.According to the requirements of the compression ratio and the filling rate range,the matching design of the rectangular rubber sealing ring and the rectangular sealing groove in the environment of temperature change proposed in this paper has certain engineering guiding significance.
