轻型汽车QX1060驱动桥壳的有限元分析毕业论文.doc

湖北汽车工业学院毕业论文PAGEPAGEV毕业论文轻型汽车QX1060驱动桥壳的有限元分析摘要作为汽车的主要承载件和传力件，驱动桥壳承受了载货汽车满载时的大部分载荷，而且还承受由驱动车轮传递过来的驱动力、制动力、侧向力等，并经过悬架系统传递给车架和车身。因此，驱动桥壳的研究对于整车性能的控制是很重要的。本文以轻型载货汽车QX1060驱动桥壳为研究对象，详细论述了从UG软件中的参数化建模，到ANSYS中有限元模型的建立、边界条件的施加等研究。并且通过对桥壳在四种主要工况下的静力分析和模态分析，直观地得到了驱动桥壳在各对应工况的应力分布及变形情况。从而在保证驱动桥壳强度、刚度与动态性能要求的前提下，为桥壳设计提出可行的措施和建议。关键词：有限元法，UG，ANSYSWorkbench，驱动桥壳，静力分析，模态分析AbstractAsthemainlycarryingandpassingcomponentsofthevehicle,theautomobiledriveaxlehousingsupportstheweightofvehicle,andtransfertheweighttothewheel.Throughthedriveaxlehousing,thedrivingforce,brakingforceandlateralforceactonthewheeltransfertothesuspensionsystem,frameandcarriage.ThisarticlestudiesbasedonlighttruckdriveraxleofQX1060,discussesindetailfromtheUGsoftwareparametricmodeling,establishofANSYSFEMmodel,andtheboundaryconditionsimposed,etc.Andthroughdriveaxlehousingofthefourmainconditionsofstaticanalysisandmodalanalysis,itcanaccessthestressdistributionanddeformationinthecorrespondingstatusofdriveaxledirectly.Thus,underthepremiseofensuringthestrengthofdriveaxlehousing,stiffnessanddynamicperformancerequirements,theanalysiscanraisefeasiblemeasuresandrecommendationsindriveaxlehousingdesign.Keywords：Finiteelementmethod，UG，ANSYSWorkbench，Driveaxlehousing，Staticanalysis，Modalanalysis目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc170581749"摘要PAGEREF_Toc170581749\hIHYPERLINK\l"_Toc170581750"AbstractPAGEREF_Toc170581750\hIIHYPERLINK\l"_Toc170581751"1绪论PAGEREF_Toc170581751\h1HYPERLINK\l"_Toc170581752"1.1课题来源及意义PAGEREF_Toc170581752\h1HYPERLINK\l"_Toc170581753"1.2国内外研究现状PAGEREF_Toc170581753\h1HYPERLINK\l"_Toc170581754"1.3ANSYS软件介绍PAGEREF_Toc170581754\h4HYPERLINK\l"_Toc170581755"1.3.1概述PAGEREF_Toc170581755\h5HYPERLINK\l"_Toc170581756"1.3.2ANSYS的主要模块及功能PAGEREF_Toc170581756\h5HYPERLINK\l"_Toc170581757"1.3.3ANSYS的主要技术特点PAGEREF_Toc170581757\h6HYPERLINK\l"_Toc170581758"1.3.4ANSYSWorkbench简介PAGEREF_Toc170581758\h7HYPERLINK\l"_Toc170581759"1.4CAD/CAE在汽车设计中的应用PAGEREF_Toc17058175
