【摘要】：碳纤维增强复合材料具有比强度高、比模量高、耐腐蚀性好等诸多优异性能,在汽车结构中得到了广泛的应用。利用Altair OptiStruct软件建立了电池壳体有限元模型,对汽车蓄电池壳体结构进行了优化设计。整个汽车蓄电池壳体优化过程包括三个阶段:概念设计阶段、系统设计阶段、详细设计阶段。首先,在概念设计阶段利用自由尺寸优化模块确定了铺层块的形状;然后,在系统设计阶段利用尺寸优化模块完成了铺层厚度的优化;最后,在详细设计阶段利用铺层顺序优化模块完成了铺层顺序的优化。优化结果表明,通过优化设计能减轻电池壳体的重量,减重比高达66%,优化效果明显。
[Abstract]:Carbon fiber reinforced composites (CFRP) have been widely used in automobile structures because of their high specific strength, high specific modulus and good corrosion resistance. The finite element model of battery shell is established by using Altair OptiStruct software, and the optimum design of automobile battery shell structure is carried out. The whole optimization process includes three stages: conceptual design, system design and detailed design. Firstly, in the conceptual design phase, the free dimension optimization module is used to determine the shape of the layering block; then, in the system design phase, the layer thickness is optimized by using the dimension optimization module. In the detailed design phase, the layer sequence optimization module is used to optimize the layering order. The optimization results show that the weight of the battery shell can be reduced by the optimum design, and the weight loss ratio is as high as 66. The optimization effect is obvious.
