摘要
以纯电动汽车的电池包为研究对象,通过GB 38031-2020确定其冲击载荷,进行有限元分析。利用OptiStruct对电池包进行瞬态响应计算,结果表明在7 ms时,电池包的吊耳及螺栓处的最大应力为167.5 MPa,小于材料抗拉强度270 MPa,符合设计要求。在开发初期应用有限元分析方法进行电池包的瞬态响应分析,有利于缩短电池包设计周期并降低成本。
Taking the battery pack of battery electric vehicles as the research object,the impact load is determined through GB 38031-2020 and perform finite element analysis.The transient response calculation of the battery pack is carried out using OptiStruct,and the results show that at 7 ms,the maximum stress at the lifting lug and bolt of the battery pack is 167.5 MPa,which is less than the material tensile strength of 270 MPa and meets the design requirements.Applying finite element analysis method for transient response analysis of battery packs in the early stages of development is beneficial for shortening the battery pack design cycle and reducing costs.
