摘要
为了解决电动汽车的续航和强度刚度问题,以某汽车的电池箱为研究对象,实际测量尺寸并在CATIA中建模后导入ABAQUS建立仿真模型,进行电池箱的2种组合工况下的静强度和约束模态分析。针对电池箱的仿真分析结果,再使用碳纤维复合材料T300/5222进行材料替代,运用等代设计法对T300/5222的厚度进行设计以及铺层角度确定,结果表明,复合材料电池箱的动静态性能提高,电池箱质量降低,轻量化效果显著。
In order to solve the problem of battery life and strength rigidity of electric vehicles, the battery box of a certain car was taken as the research object. The actual measurement size was modeled in CATIA and then imported into Abaqus to establish a simulation model for static strength and constrained modal analysis of battery box under two combined working conditions. According to the simulation analysis results of the battery box, the carbon fiber composite material T300/5222 was used for material substitution, the thickness of T300/5222 was designed by the equivalent design method, and the layering angle was determined. The results show that the dynamic and static performance of the composite battery box is improved, the mass of the battery box is reduced, and the lightweight effect is significant.
