湖南工业大学本科生毕业设计(论文)学科门类:单位代码:毕业设计说明书(论文)低速载货汽车车架及悬架系统设计学生姓名所学专业班级学号指导教师XXXXXXXXX系二○**年XX月湖南工业大学本科生毕业设计(论文)摘要本课题结合生产实际,在农用运输车的基础上对低速载货汽车车架及悬架系统进行了设计。设计内容主要包括:参与总体设计;车架、悬架结构型式分析和主要参数的确定;车架、悬架结构设计。整个设计过程遵循以下原则和技术标准:规范合理的型式和尺寸选择,结构和布置合理;保证整车良好的平顺性能。工作可靠,结构简单,装卸方便,便于维修、调整;尽量使用通用件,以便降低制造成本;在保证功能和强度的要求下,尽量减小整备质量。低速载货汽车上用得比较广泛的是边梁式车架和非独立悬架,因为边梁式车架和非独立悬架结构简单,比较经济实用,便于维修和改装。考虑到车架和悬架在整车设计中的作用,首先进行了车架、悬架的总体设计,然后对车架、悬架结构进行了设计,最后对车架、悬架的结构进行了受力综合分析,在次基础上确定了它们的主要参数。关键词:低速货车,车架,悬架,设计谢谢朋友对我文章的赏识,充值后就可以下载说明书。我这里还有一个压缩包,里面有相应的word说明书(附带:外文翻译、调研报告)和CAD图纸。需要压缩包的朋友请联系QQ客服:1459919609。下载后我可以将压缩包免费送给你。需要其他设计题目直接联系!!!湖南工业大学本科生毕业设计(论文)ABSTRACTThistopiccombinedproductionwiththeactualandbasedontheagriculturetransportvehiclefoundation,thelowspeedtruckframeandsuspensionsystemhavebeendesigned.Themaincontentofthedesigninclude:thedesignoftheparticipationsystem,analysisofthestructurepatternoftheframeandsuspensionanddeterminationofthemainparameter,designofthestructureoftheframeandsuspension.Duringtheentiredesignprocess,theprinciplesandthetechnicalstandardsarefollowed:thereasonablepatternandthesize,thestructureandarrangement;thegoodsmoothperformanceoftheentirevehicle;withreliablework,simplestructure,loadingandunloading,advantageousfortheserviceandtheadjustment;asfaraspossiblegeneralparts,inordertoreducethecostoftheproduction,thefunctionandtheintensityrequestareguaranteed,thequalityisreducedasfaraspossible.Thesideframeandnon-independentsuspensionareusedquitewidelyonthelowspeedtruck,becausethesideframeandnon-independentsuspensionstructurearesimple,economicalandpractical,advantageousfortheserviceandtherefit.Consideredthefunctionoftheframeandsuspensionintheentirevehicledesign,firstlythatthewholeoftheframeandsuspensionsystemiscarriedondesigning,thenthestructureoftheframeandsuspensionhavebeencarriedondesigning,finallythestressgeneralizedanalysisofthestructureoftheframeandsuspensionhasbeencarriedon,theirmainparameterhasbeendeterminedintheinferiorfoundation.Keywords:LowSpeedTruck,Frame,Suspension,design湖南工业大学本科生毕业设计(论文)目录第1章前言...................................................................................................................1第2章总体方案论证.................................................................................................22.1设计选型原则.............................................................................................................22.2设计内容.....................................................................................................................3第3章主要尺寸参数的选定....................................................................................33.1外廓尺寸.....................................................................................................................33.2质量参数.....................................................................................................................3第4章车架总成设计..................................................................................................44.1车架的结构设计.........................................................................................................44.2车架的技术要求.........................................................................................................5第5章车架的设计计算..............................................................................................65.1车架的计算..................................................................................................................65.2车架载荷分析.............................................................................................................85.3车架弯曲强度的计算.................................................................................................85.4车架扭转应力的计算...............................................................................................11第6章悬架的总成设计............................................................................................146.1悬架的设计要求........................................................................................................146.2悬架的两种形式........................................................................................................146.3悬架主要参数的确定................................................................................................176.4钢板弹簧的设计........................................................................................................20结论...................................................................................................................................23参考文献...................................................................................................................24致谢...............................................................................................................................25湖南工业大学本科生毕业设计(论文)第1章前言车架和悬架系统是汽车设计的重要部分,因为它们的好坏直接关系到汽车各个方面(操控、性能、安全、舒适)性能。现代汽车绝大多数都具有作为整车骨架的车架。汽车绝大多数部件和总成都是通过车架来固定其位置的,如发动机、传动系统、悬架、转向系统、驾驶室、货箱和有关操纵机构。车架是支撑连接汽车的各零部件,并承受来自车内、外的各种载荷,所以在车辆总体设计中车架要有足够的强度和刚度,以使装在其上面的有关机构之间的相对位置在汽车行驶过程中保持不变并使车身的变形最小,车架的刚度不足会引起振动和噪声,也使汽车的乘坐舒适性、操纵稳定性及某些机件的可靠性下降。过去对车辆车架的设计与计算主要考虑静强度。当今,对车辆
