本科生毕业设计（论文）PAGEIII摘要本次设计题目是CA1092A货车的前后悬架系统的设计。所设计悬架系统的前悬架采用钢板弹簧非独立式悬架。后悬是由主副簧组成，也是钢板弹簧非独立式悬架，然后对主要性能参数进行确定。在前悬的设计中首先设计了钢板弹簧，包括弹簧断面形状的选择，主要参数的确定，材料和许用应力的校核，和方案布置的设计；还有减振器的选择。在后悬架系统设计中主要对主副钢板弹簧进行了设计。最后对悬架系统进行了平顺性分析，目的是判断所设计的悬架平顺是否满足要求。结是没有不舒适。因而对提高汽车的动力性、经济性和操纵稳定性是有利的。关键词：悬架设计；钢板弹簧；平顺性；货车AbstractThetitleofthisthesisisthedesignoffrontandrearsuspensionsystemsofCA1092Atruck.Thefrontsuspensionsystemistheleafspring,dependentsuspension.Therearsuspensionsystemconsistsofthemainspringandthehelperspringanditisalsotheleafspring,dependentsuspension.Intheprocedureofthedesignwemadecertainthestructuralstyleofthesuspensionsysteminthefirst,thenwemadecertainthemainparameters.Inthedesignofthefrontsuspensionwedesignedtheleafspringfirstly,includingtheselectionofsectionshapeofleafspring,madecertainthemainparameters,materialandallowablestressandthedesignofscheme,moreoverthedesignofshockabsorber.Inthedesignofrearsuspensionwecarriedoutthedesignofthemainspringandthehelperspring.Inthefinaldesignstage,weimplementtheanalysisofsuspensionrideperformance.Theaimiswhethersuspensionridequalitymeetstotheperformancerequirement.Theresultsindicatethatthereisnouncomfortablenessforthecaronroad.Therefore,itishelpfulforthedynamical,economicalandhandlingperformancesofthestudiedvehicle.Keywords:SuspensionDesign;Leafspring;RidePerformance;Truck目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc170539197"第1章绪论PAGEREF_Toc170539197\h1HYPERLINK\l"_Toc170539198"第2章悬架系统的结构与分析PAGEREF_Toc170539198\h3HYPERLINK\l"_Toc170539199"2.1悬架的功能和组成PAGEREF_Toc170539199\h3HYPERLINK\l"_Toc170539200"2.2汽车悬架的分类PAGEREF_Toc170539200\h3HYPERLINK\l"_Toc170539201"2.3悬架的设计要求PAGEREF_Toc170539201\h4HYPERLINK\l"_Toc170539202"2.4悬架主要参数PAGEREF_Toc170539202\h4HYPERLINK\l"_Toc170539203"2.4.1悬架的静挠度fcPAGEREF_Toc170539203\h4HYPERLINK\l"_Toc170539204"2.4.2悬架的动挠度fdPAGEREF_Toc170539204\h5HYPERLINK\l"_Toc170539205"2.4.3悬架弹性特性PAGEREF_Toc170539205\h5HYPERLINK\l"_Toc17053920
