Abstract: In order to solve the problems of leakage for connections of the braking system in the process of filling ,the principle of sealing was investigated to analyze the cause of leakage .Firstly，using the software of ANSYS, the relation between difference size of two groups and the sealing was established.According to the analysis results,the charts of displacement vector sum of every group were compared to find the main reason of the infiuence of horn mouth of sealing. Then, the conclusion was utilized to the improvement of production technology. Finally, the sealing was tested on the automobile.The research result shows that, the diffence of taper is the primary cause,and the performance of sealing is improved obviously after improvement.
