摘要
电池包在整车行驶过程中会受到挤压和冲击载荷的作用,在产品设计开发阶段,基于正确的有限元仿真分析可以有效地考察电池包箱体和零部件是否满足机械性能要求。建立了电池包精细化有限元模型,通过对比电池包扫频实验和有限元模态分析结果,可以获得准确的有限元模型,并利用有限元仿真分析手段分别对电池包进行了两个水平方向的挤压和竖直方向机械冲击分析。
The battery pack will be crushed and impacted during the whole vehicle driving process.During the product design and development stage,based on the correct finite element simulation analysis,it can effectively investigate whether the battery pack case and components meet the mechanical performance requirements.A refined finite element model of the battery pack was established.By comparing the frequency sweep experiments of the battery pack with the analysis results of the finite element modal,an accurate finite element model could be obtained.The finite element analysis method was used to analyze the battery pack under the condition of horizontal squeeze and vertical mechanical shock.
