Today, the technology at home and abroad in the field of electric vehicles in the rapid development, some wellknown big car panies have developed different types of electric products available. But while electric vehicles into your life, you also need to solve a lot of problems. In this thesis, the dynamic parameters of the lowspeed pure electric vehicles, calculation and simulation, the main parameters are calculated based on the performance requirements of the lowspeed pure electric vehicles and matching custom conditions calculation models, the establishment of the simulation model, and in the AVLcruise software simulation, the simulated dynamic performance, verify the calculated parameters, the model the dynamic performance of electric vehicles。 does not consider issues related to economic, technical analysis corresponding to the maximum speed, driving mileage, maximum acceleration, average speed and other factors。 further research and to explore the main driving force to determine these parameters, the design and simulation of dynamic parameters design a viable lowspeed pure electric vehicles. Key words： Lowspeed electric vehicle； powertrain； The parameter match； Cruise simulation. 目 錄 1 緒 論 ............................................................................................................................... 1 引言 ......................................................................................................................... 1 國內外電動汽車發(fā)展現(xiàn)狀 ..................................................................................... 1 國外電動汽車發(fā)展現(xiàn)狀 ............................................................................. 1 國內電動汽車發(fā)展現(xiàn)狀 ............................................................................. 2 本文研究的意義 ..................................................................................................... 3 本文的主要內容 ..................................................................................................... 4 2 電動汽車的基本結構 ....................................................................................................... 5 電動汽車的基本組成 ............................................................................................. 5 電源與電池管理系統(tǒng) ................................................................................. 5 電機驅動系統(tǒng) ............................................................................................. 7 傳動系統(tǒng) ..................................................................................................... 9 底盤和車身 ................................................................................................. 9 輔助設施 ................................................................................................... 10 本章小結 ............................................................................................................... 10 3 傳動系參數(shù)設計 ............................................................................................................. 12 概述 ....................................................................................................................... 12 驅動力 ....................................................................................................... 12 行駛阻 力 ................................................................................................... 13 參數(shù)計算 ............................................................................................................... 15 電機參數(shù)設計 ....................................................................................................... 15 電動機額定功率 ....................................................................................... 15 電動機加速性能 ....................................................................................... 16 電池參數(shù)的確定 ................................................................................................... 17 本章小結 ............................................................................................................... 18 4 建立整車仿真模型 ......................................................................................................... 19 AVL CRUISE— 車輛動力學仿真分析平臺 ........................................................... 19 電機模型的建立 .....................
