1、车辆与动力工程学院毕业设计说明书 毕 业 设 计（论 文） 题目 大学生方程式混合动力电动赛车设计 2013年 5 月30 日大学生方程式混合动力电动赛车设计摘 要本次毕业设计，我进行了大学生方程式混合动力电动赛车的总体设计。在设计中，主要运用了对比分析的方法，各项参数通过优化设计和UG、MATLAB等进行优化。我根据2012年大学生方程式汽车大赛规则确定了赛车整体布置方案，并进行论证与分析，初步确定混合动力电动赛车主要参数。通过计算与对比，确定发动机型号和电动机型号,并确定其混合形式并联式。初选传动系最大传动比、最小传动比。我设计中使用UG8.0三维软件对各个零部件总成进行建模和整体装配，并

2、进行悬架、转向的运动干涉分析。利用发动机动力特性曲线和电动机动力特性曲线特点，用MATLAB软件绘制出混合动力电动赛车驱动力-行驶阻力平衡图、加速度曲线图等，并详细计算混合动力电动赛车的燃油经济性。利用UG8.0进行导出混合动力电动赛车总体布置二维工程图，并制成总体参数表，并将纯发动机赛车与此次混合动力电动赛车进行对比分析。通过本次毕业设计，了解和掌握了对汽车进行总体设计的步骤和方法，并且使我认识到混合动力汽车的发展前景。巩固了本专业的所学的专业知识，增强了搜集资料、整合资料的能力，这些将为我毕业以后从事汽车设计工作打下良好的基础。关键词：混合动力电动赛车，参数确定，总布置，动力性，经济性Er
