本科生毕业设计（论文）PAGEIV摘要随着汽车工业的发展，人们对汽车的乘坐舒适性和安全性的要求逐渐提高，而悬架对汽车这一方面性能有很大的影响。因此对汽车的悬架系统和减振器也提出了更高的要求。本次设计主要内容是：红旗世纪星轿车的前、后悬架系统的结构设计，根据当前轿车悬架的发展情况，本设计的轿车前后悬架均采用独立悬架的形式,并且前后悬均采用比较流行的麦弗逊悬架。根据确定的结构选取悬架的自振频率，从而可以计算出悬架的刚度、静挠度和动挠度。采用以上数据计算弹性元件尺寸并且进行应力校核。在设计减振器时，根据阻尼系数和最大卸荷力来计算选取减振器的主要尺寸。然后再依次确定导向机构和横向稳定杆。在所有结构尺寸确定后采用CAXA软件绘制前后悬架的装配图和零件图。利用Matlab软件对悬架系统的平顺性进行了编程分析,论证了该系统设计方案的合理正确性，能够满足实际的需要。关键词：悬架；汽车减振器；平顺性；导向机构AbstractWiththedevelopmentoftheAutomobileindustry,peoplehavebeenpromotingtherequirementforthesafetyandridecomfortqualityofthevehicle.andsuspensionsysteminfluencethisaspectofperformancealot.Asaresult,thereisahigherdemandonthesuspensionandtheshockabsorbersystemofthevehicle.whilethecar'ssuspensionsystemalsomadehighdemands.TheprojectmainlyincludesthedesignofconstructionofHongQifrontandrearsuspensionsystem.Basedonthecurrentdevelopmentsinthecarsuspension,thedesignofthecarbeforeandafterthesuspensionareusedintheformofindependentsuspension.BeforeandafterthehangingandareusedmorepopularMcPhersonsuspension.Accordingtodeterminethestructureoftheselectedsuspensionnaturalfrequency,whichcancalculatethestiffnessofthesuspension,staticanddynamicdeflectiondeflection.Moreflexibleuseofdataofcomponentsandsizeofastresscheck.Inthedesignofshockabsorber,inaccordancewiththelargestdampingandunloadingofthetermsofthemainshockabsorberselectedsize.ThenbodieswereidentifiedandhorizontalorientationWendingGan.whenallstructuresizearedetermined,usingCAXAmappingsoftwareinbeforeandafterthesuspensionoftheassemblyandpartsplans.Matlabsoftwareprogramminganalysiswasusedintheridesuspensionsystem.,demonstrationofthesystemdesignofreasonableaccuracy,tomeettheactualneeds.Keywords:Suspension;Automobileshockabsorber;Ridecomfort;Guidemechnism目录TOC\o"1-3"\f\h\zHYPERLINK\l"_Toc264742041"第1章绪论PAGEREF_Toc264742041\h1HYPERLINK\l"_Toc264742042"1.1悬架简介PAGEREF_Toc264742042\h1HYPERLINK\l"_Toc264742043"1.2设计要求：PAGEREF_Toc264742043\h1HYPERLINK\l"_Toc264742044"第2章前、后悬架结构的选择PAGEREF_To
