毕业设计（论文）-纯电动车的动力系统参数.docVIP

2015届湖北汽车工业学院毕业设计（论文）摘要由于环境污染、能源匮乏等问题日益严重，电动汽车成为汽车行业研究的热点。纯电动汽车动力传动系部件参数的合理匹配，对电动汽车的动力性和经济性等有显著的影响。本文以某轻型纯电动客车为研究的对象，主要介绍了电动汽车动力传动系统相关理论匹配的方法，动力传动系统主要部件的性能要求，以及影响整车性能的因素分析等。根据整车的性能要求及部件的选型原则，对该纯电动客车的动力系统参数进行设计计算，实现传动系统参数的合理匹配。最后利用MATLAB软件对所选的一些参数进行验算，检验参数是否满足整车的性能要求。关键词：纯电动客车；动力传动系统；参数匹配；动力性；经济性 AbstractDue to environmental pollution, energy shortages and other problems have become increasingly serious,the electric vehicle has become the hot spot .The reasonable matching of the parameters of the power transmission parts has a significant effect on the dynamic and the economy of the electric vehicle.Taking a light electric buses as the object in this article. It introduces the theory of electric vehicle power train matching method performance .It also describes the performance requirements of major power train components.It also analyzes the factors that affect vehicle performance analysis, etc.According to the vehicle performance requirements and components selection principle, the power system parameters of the pure electric bus are designed and calculated, and the parameters of the transmission system are reasonably matched.Finally,the MATLAB software is used to test the performance of the vehicle.Keywords: pure electric bus；power system；parameter matching；dynamic；economy 目录TOC \o 1-3 \h \u HYPERLINK \l _Toc15318 第一章 绪论 PAGEREF _Toc15318 1 HYPERLINK \l _Toc27668 1.1 课题研究的背景 PAGEREF _Toc27668 1 HYPERLINK \l _Toc12742 1.2 课题研究的意义 PAGEREF _Toc12742 1 HYPERLINK \l _Toc28831 1.3 汽车动力传动系统匹配方法现状研究 PAGEREF _Toc28831 2 HYPERLINK \l _Toc2744 1.4 本论文研究的主要内容 PAGEREF _Toc2744 4 HYPERLINK \l _Toc25905 第二章 电动汽车的基本结构及关键技术 PAGEREF _Toc25905 5 HYPERLINK \l _Toc5477 2.1 电动汽车的基本结构及工作原理 PAGEREF _Toc5477 5 HYPERLINK \l _Toc22556 2.2 电动汽车的关键技术 PAGEREF _Toc22556 6 HYPERLINK \l _Toc8044 2.2.1 电机及其控制技术 PAGEREF _Toc8044 6 HYPERLINK \l _Toc16077 2.2.2 电池及其充电技术 PAGEREF _Toc16077 7 HYPERLINK \l _Toc21928 2.2.3 能量管理技术 PAGEREF _Toc21928 8 HYPERLINK \l _Toc29516 2.3 本章小结 PAGEREF _
