摘要
采用ANSYS软件,建立电动汽车全塑车身覆盖件有限元分析模型。车身主体材料采用长玻纤增强聚丙烯PP-LGF,在水平行驶、悬空、紧急制动、急转弯等4种极限行驶状态下对车身进行了强度分析和模态分析,验证了强度和振动满足车身要求。静力学分析和模态分析结果为车身拓扑优化提供了基础参考数据,也是后续电动汽车车身结构进行轻量化改进的基础。
The finite element analysis model for the plastic body panels of electric vehicles is established by using ANSYS software.The body material is long glass fiber reinforced polypropylene PP-LGF, the Strength and modal of the car body are analyzed under four extreme driving states such as horizontal driving、 suspension、 emergency braking and sharp turning,and it was verified that the strength and vibration meet the requirements of the car body. The results of static and modal analysis provide basic reference data for body topology optimization, and are also the basis for subsequent lightweight improvements of electric vehicle body structures.
