毕业设计（论文） 题目 大学生F1方程式赛车整车设计 专业 车辆工程 班级 学号 学生 指导教师 　二○一三 年 大学生F1方程式赛车整车设计 摘要 本文基于汽车理论课程实践所做的BAJA赛车模型，并结合FSAE赛车比赛规则和赛道的布置特点，进行拓展设计一款大学生F1方程式赛车。从赛车底盘角度出发，本文侧重于汽车车架的设计，因为车架是整车的重要组成部分，它不仅承受着来自路面的各种复杂载荷，同时也是其他总成的安装载体。通过有限元法对车架结构进行分析，对提高整车的各种性能有重要的意义。本文根据《中国FSC大赛规则（2012）》要求，首先利用UG6.0软件对赛车车架进行结构设计，建立起多个车架的三维模型，然后将设计出来的多个车架以及BAJA模型的车架导入到有限元软件中，对车架进行静力学分析，通过对比静力和应力分布图分析选出更优秀的车架。同时对Formula SAE 赛车的发动机系统、车轮系统、传动系统、悬架系统、转向系统、制动系统等进行选型和整体布置，然后根据所选的总成参数对整车动力性能进行匹配以及整车动力性能进行分析，从而设计出一款符合大赛要求同时性能优异的赛车。 关键词：UG，大学生F1方程式赛车，车架，有限元分析，动力匹配 Formule SAE Collegiate Design of The Racing Car ABSTRACT The article is Based on the BAJA racing car model which is made at the Practice of Automobile Theory Course , and at the same time with combinations of the FSAE car racing game rules and the circuit layout characteristics, to expand the design of a formula sae race car. Start from the chassis of the car , this article focuses on the design of automobile frame, because the frame is an important part of vehicle, it not only suffered from a variety of complex surface load, at the same time it is the carrier to install the other assembly. Through the finite element method analysis of frame structure, has important significances to improve the vehicle performance. According to《 FSC contest rules (2012) of the Peoples Republic of China》 requires, first of all, using the software of UG6.0 to carrry out on the car frame structure design, setting up multiple 3 d model of the frame, and then imported multiple frame and BAJA model frame into the finite element software, using the statics to analysis the frame, by comparing the static and stress distribution analysis to select the better frame. To select the type of Formula SAE racing car engine system, the wheel system,the transmission system, the suspension system, the steering system and the brake system and layout of the whole, and then according to the parameters of the selected to match the vehicle dynamic performance an
