电动汽车某连接器弹片式接触端子的优化设计

Optimization Design of Shrapnel Contact Terminal for Connector of Electric Vehicle

以弹片式接触端子装配时的插入力、拔出力和应力为质量特性,以端子使用后不会产生永久变形为目标,利用响应曲面法与有限元分析法完成优化设计,利用统计软件Minitab以线性回归方法建构模型,验证了采用响应曲面法建立的回归模型具有良好的预测性。

Taking the assembly insertion force,pull out force and stress as quality characteristics,taking the terminal not produce permanent deformation as the goal,the response surface method and the finite element analysis were used to make optimization design of the long arm of the shrapnel contact terminal,the mathematic model was built with linear regression method based on Minitab statistical software. The results verify that the regression model built with response surface method has good prediction performance.
