全承载式客车车身结构有限元分析田芳1王涛2石琴2(1江淮汽车合肥2合肥工业大学,机械与汽车工程学院合肥)摘要:以板梁单元为基础,在ANSYS中建立全承载式客车骨架的有限元模型,并通过客车骨架的电测试验验证有限元模型的正确性。对车身结构进行弯曲、扭转、扭转加制动等典型工况下。强度和变形计算。对客车骨架进行模态分析,为后续的瞬态响应分析奠定基础。关键词:客车;车身结构;有限元静态分析;模态分析FiniteelementanalysisformonocoquebusbodystrnctreTIANFang1,WANGTao2,SHIQin2(1JAC,Hefei,Anhui2SchoolofMachineryandAutomobileEngineering,HefeiUniversityofTechnology,Hefei,Anhu)iAbstract:Thefiniteelementmodelforthefull-loadingbusbodyinbuiltinANSYSsoftwarewithshellandbeamelements,andthefinite
