摘要
依据复合材料重量轻,比强度、比刚度高等优点,针对某企业现有的某型号电动汽车电池箱结构进行轻量化设计,目的是减轻该电动汽车的重量。本研究以应用软件Patran&Nastran为分析平台,利用有限元分析方法,对比钢与碳纤维/环氧树脂复合材料两种材料的电池箱结构各自的承载性能,设计了合理的碳纤维/环氧电池箱。在Tsai-wu强度理论的基础上,对碳纤维/环氧电池箱进行了强度校核。结果表明,在减轻了该电池箱64%重量的前提下,电池箱的承载性能没有降低。
According to the advantages of lightweight,high specific rigidity and strength of the composite material,it has been designed for the light weight of a certain type of electric vehicle battery box structure,which aims at reducing the weight of the electric vehicle. By applying PatranNastran as the analysis platform,this study uses the finite element analysis method to compare the bearing capacity of the battery box structures of two kinds of steel and carbon fiber / epoxy composite. Then,a reasonable structure of carbon fiber / epoxy battery box was designed. On the basis of Tsai-wu strength theory,the strength of carbon fiber / epoxy battery box was checked. Results show that the bearing performance of the battery box is not reduced under the condition of reducing the 64% weight of the battery box.
