FSAE大学生方程式赛车(电动版)设计说明书

摘要以大学生方程式赛事为背景，参考广西工学院鹿山学院大学生方程式赛车作为基础，应用汽车理论和汽车设计等相关知识结合比赛规则，对赛车的基本尺寸、质量参数和赛车的性能参数进行选择，对赛车各总成进行选型和总布置，进行赛车蓄能系统、再生制动系统以及行驶系统、传动系统进行设计。根据同组同学确定的驱动系统，结合比赛需求计算出电池、电容容量和要求，选择电池、电容型号和组合形式，确定出外形尺寸和质量和安装位置。再为蓄能装置匹配出合适的充电系统。设计节能环保的再生制动系统,然后按照鹿山二号对纯电动方程式赛车的行驶系统、传动系统进行改动,最后再结合同组同学的参数，确定整车的设计参数。随着全球能源、环境问题的日益严峻，节能环保的纯电动车辆将会成为下一个时代的主流。关键词：大学生方程式赛车；总布置；磷酸铁锂电池；超级电容广西工学院鹿山学院本科生毕业设计（论文）1AbstractStudentsFormulaOneracingeventsasthebackground,refertotheGuangxiInstituteofTechnologytheKayamaCollegeStudentsFormulaOneracingasabasisfortheautomotivedesignandautomotivetheoryandotherrelatedinformationaswellastheFSAEcompetitionrules，applicationofautomotivetheoryandknowledgeofautomotivedesign,combinedwiththerulesofthegame,thebasicdimensionsofthecar,qualityparametersandperformanceparametersofthecarselection,selectionandgeneralarrangementoftheassemblyofthecar,thecarenergystoragesystem,regenerativebrakingsystemanddrivingsystem,transmissionsystemdesign.Accordingtothesamegroupofstudentstodeterminethedrivesystem,combinedwiththegameneedstocalculatethebattery,capacitor,capacityandrequirements,selectthebattery,capacitormodelandthecombinationtodeterminetheshapesizeandquality,andinstallationlocation.Matchthechargingsystemfortheenergystoragedevice.Theregenerativebrakingsystemofthedesignofenergysavingandenvironmentalprotection,andthenfollowtheLushanIIFormulaOneracingforpureelectricdrivingsystem,thetransmissionsystemtomakechanges,andfinallycombinedwiththeparametersofthesamegroupofstudentstodeterminethedesignparametersofthevehicle.Keywords:collegestudentsandFormulaOneracing;generalarrangement;lithiumironphosphatebatteries;supercapacitor广西工学院鹿山学院本科生毕业设计（论文）2目录1绪论.................................................................41.1大学生方程式赛事介绍...........................................41.2大学生方程式的历史.............................................41.3赛事意义.......................................................51.4国内外发展现状.................................................52纯电动方程式赛车总布置设计...........................................62.1赛车主要参数的选取.............................................62.1.1纯电动方程式赛车机械部分参数的选取........................62.1.2赛车性能参数的选取........................................72.1.3悬架主要参数（学院车队提供）..............................82.2赛车驱动电机的选取.............................................82.2.1电机类型的选择............................................82.2.2电机功率的选择............................................92.3赛车各总成选型原则和总布置....................................102.3.1悬架、轮胎的选择.........................................102.3.2制动系统.................................................102.3.3车架.....................................................112.4人机工程......................................................112.4.1人体尺寸.................................................112.5赛车的轴荷分配................................................122.5.1学院鹿山2号的轴荷分配...................................122.5.2纯电动方程式赛车相对后轴增加的质量分布的计算.............132.5.3纯电动方程式赛车轴荷的分配...............................133储能装置的选择......................................................143.1蓄能装置的容量计算............................................143.1.1赛车的续驶里程...........................................143.1.2蓄能器容量的计算.........................................143.2蓄能装置类型的选择............................................143.2.1高比能量蓄能装置.........................................143.2.2高比功率储能设备的选择...................................173.2.3高比功率装置的计算.......................................173.2.4超级电容的计算...........................................224充电器的设计.......................................................244．1锂离子电池充电方法...........................................244.1.1常用的充电方法[10].........................................244.1.2赛车充电放式的选取.......................................254．2赛车的充电要求...............................................254.2.1赛车的充电要求...........................................254.2.2充电器方框图.............................................264.2.3充电器的分析.............................................275再生制动............................................................295.1赛车制动力矩的计算............................................29广西工学院鹿山学院本科生毕业设计（论文）35.1.1赛车制动力的要求.........................................295.1.2赛车制动力的计算........................................295.2制动距离和制动减速度..........................................305.2.1制动减速度计算...........................................305.2.2制动距离计算.............................................315.3制动效能的恒定性..............................................315.4制动的稳定性..................................................315.5前、后制动器制动力的比例关系..................................315.5.1求出I曲线...............................................315.5.2具有固定比值的前、后制动器制动力分析.....................325.6赛车要求的最大制动力..........................................335.6.1赛车最高车速下所具有的能量...............................335.6.2塞车的制动力要求.........................................345.6.3赛车制动器制动力的选取...................................345.6.4赛车再生制动路线分析.....................................366机械传动系统与行驶系................................................376.1机械传动系统....................
