| 摘 要： | 首先对蓄电池支架的结构组成进行了简单的阐述,并将蓄电池支架按照与白车身的连接形式分为焊接式和安装式两种结构.然后选取四种车型的蓄电池支架,进行其结构对比与分析,同时通过CAE有限元分析比较了4种蓄电池支架在X,Y,Z三个方向上的动刚度值,结果得出焊接式蓄电池支架的动刚度值相对安装式的要高,同时蓄电池支架的悬臂设计长度对其动刚度大小有重要的影响.

| Abstract: | The structural components of a battery bracket are first discussed in this article. Moreover, the battery bracket is divided into welding-type structure and mounting-type structure based on connection mode with BIW. And then battery brackets are selected from four vehicles for structural comparison and analysis. At the same time, dynamic stiffness values of four battery brackets are compared in X-axis direction, Y-axis direction and Z-axis direction via CAE finite element analysis. The result indicates that dynamic stiffness value of welding-type battery bracket is higher than that of mounting-type battery bracket. Meanwhile, design length of battery-bracket arm has a significant effect on its dynamic stiffness. |
