FSAE大学生方程式赛车(电动版)设计说明书 下载本文

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。

Abstract

Students Formula One racing events as the background, refer to the Guangxi Institute of Technology the Kayama College Students Formula One racing as a basis for the automotive design and automotive theory and other related information as well as the FSAE competition rules,application of automotive theory and knowledge of automotive design , combined with the rules of the game , the basic dimensions of the car , quality parameters and performance parameters of the car selection , selection and general arrangement of the assembly of the car , the car energy storage system , regenerative braking system and driving system, transmission system design.

According to the same group of students to determine the drive system , combined with the game needs to calculate the battery, capacitor , capacity and requirements , select the battery, capacitor model and the combination to determine the shape size and quality , and installation location . Match the charging system for the energy storage device . The regenerative braking system of the design of energy saving and environmental protection , and then follow the Lushan II Formula One racing for pure electric driving system , the transmission system to make changes , and finally combined with the parameters of the same group of students to determine the design parameters of the vehicle .

Keywords: college students and Formula One racing ; general arrangement ; lithium iron phosphate batteries ; super capacitor
