摘要院为减小外力对高压电池包产生的应力与变形,对电池包上盖、托盘及支架所受应力变形进行了分析。文章建立了高压电池包模型,依据有限元理论,对高压电池包进行静力学和模态分析,并对电池包进行碰撞应力分析。以电池包上盖、托盘及支架的厚度为设计变量,以减小电池包在外力作用下的应力与变形为目标,对电池包进行结构优化,并通过仿真分析验证优化结果。实验结果表明:优化后的电池包所受最大应力与变形明显下降,电池包的碰撞安全性得到提高。关键词院高压电池包曰静力学曰碰撞曰优化中图分类号院U469.7文献标识码院A文章编号院2095原0926(圆园23)03原园园31原园6OptimizationdesignofbatterypackforhybridelectricvehiclesZHANGYang袁ZHANGLei袁WANGYao袁WANGQing袁LIYajuan渊SchoolofAutomobileandTransportation袁TianjinUniversityofTechnologyandEducation袁Tianjin300222袁China冤Abstract院Toreducethestressanddeformationcausedbyexternalforceonthehigh-voltagebatterypack袁analysiswascarriedoutonthestressanddeformationofthebatterypackcover袁trayandsupport.Amodelofthehigh-voltagebatterypackwasestablished袁andbasedonthefiniteelementtheory袁thestaticanalysis袁modalanalysisandcollisionstressanalysiswereperformedonthebatterypack.Takingthethicknessofthebatterypackcover袁trayandsupportasdesignvariables袁thestructuraloptimizationofthebatterypackwasperformedtoreducethestressanddeformationofthebatterypackundertheexternalforce袁andtheoptimizationresultswereverifiedbysimulationanalysis.Theexperi鄄mentalresultsshowthatthemaximumstressanddeformationoftheoptimizedbatterypackdecreasesignificantly袁andthesafetyofthebatterypackisimproved.Keywords院high-voltagebatterypack曰statics曰collision曰optimization混合动力汽车电池包优化设计张扬,张蕾,王瑶,王清,李亚娟(天津职业技术师范大学汽车与交通学院,天津300222)收稿日期院2023-05-15基金项目院天津市科技计划项目(21YDTPJC00400);天津市研究生科研创新项目(2022SKYZ052).作者简介院张扬(1985—),男,硕士研究生,研究方向为优化设计.通信作者:张蕾(1975—),女,教授,博士,博士生导师,研究方向为汽车设计,zldeg@126.com.随着人们对新能源汽车需求的与日俱增,车辆保有量不断增加,交通事故率也随之增长...
