混联式电动汽车再生制动系统试验台设计 摘 要 电动汽车的再生制动，就是利用电机的电气制动产生反向力矩使车辆减速或停车。对于感应电机来说，电气制动有反接制动、直流制动和再生制动等。其中，能实现将刹车过程中能量回收的只有再生制动，其本质是电机转子的转动频率超过电机的电源频率，电机工作于发电状态，将机械能转化为电能通过逆变器的反向续流二极管给 Abstract Electric vehicle regenerative braking, reverse torque developed is the use of electric braking of the motor vehicle to slow down or stop. For induction motor, the electric braking is dc braking and regenerative braking, reverse connect braking, etc. Which can achieve the braking energy recovery is only in the process of regenerative braking, its essence is the power of the motor rotor rotational frequency over the frequency, the motor working in power state, convert mechanical energy into electrical energy through the inverter the reverse of the fly-wheel diode recharge energy storage device. This paper briefly introduces the kinds of regenerative braking system and its development process, and analyzes the domestic and foreign research status and development trend of regenerative braking system, master the principle, design a regenerative braking system test bench. Test stand is mainly achieved by a stepless speed change device transmission ratio of the change, cooperate with other devices, to achieve energy recovery. Among them, the core device, use CAD draw its principle diagram, and using CATIA three-dimensional modeling software. Finally to summarize their work, this paper discusses the design scheme of the problem4, and the further work is prospected. Key words: Regenerative braking system, test bench, stepless transmission, model 目录 摘 要 I Abstract II 引 言 1 第1章 绪论 2 1.1再生制动系统研究背景 2 1.2再生制动研究现状 2 1.3再生制动系统研究意义 2 第2章 再生制动系统原理及分类 4 2.1再生制动的分类 4 2.1.1飞轮储能式制动能量再生系统 4 2.1.2液压储能 5 2.1.3电化学储能 5 第3章 实验台方案设计 7 3.1实验台整体布置 7 3.2试验台主要装置 8 3.2.1无级变速器 8 3.2.2飞轮 9 3.2.3电机 9 3.2.4蓄电池 10 3.2.5功率变换器 10 3.3混合动力系统与CVT融合的技术优势 10 第4章 试验台CVT三维模型的建立 12 4.1、CATIA软件介绍 12 4.2、CVT建模过程 12 4.2.1、主动工作缸建模 12 4.2.2、从动工作轮建模 16 4.2.3、金属传动带建模 18 4
