【摘要】:大學生方程式汽車大賽(FSAE)是以培養(yǎng)汽車工業(yè)技術(shù)人才與其他機械技術(shù)人才為目的,為在校大學生提供將所學理論知識運用的實踐的競賽。2010年大學生方程式汽車大賽正式落戶中國,從此大學生方程式汽車大賽在中國不斷發(fā)展壯大,2013年中國方程式汽車大賽又將純電動賽車納入正式競賽,如今中國大學生方程式汽車大賽已經(jīng)成為中國工科類大學參與最廣的競賽項目之一。動力系統(tǒng)是賽車的核心,決定賽車動力性能與競爭實力,直接影響比賽結(jié)果,因此對賽車動力系統(tǒng)匹配問題研究至關(guān)重要。本文以長安大學純電動賽車—獵電為研究對象,依據(jù)方程式競賽項目對賽車進行動力系統(tǒng)匹配,闡述了純電動賽車的基本原理,從空間結(jié)構(gòu)、機械結(jié)構(gòu)、驅(qū)動系統(tǒng)與電氣系統(tǒng)四個方面分析了方程式賽車與商用汽車的區(qū)別,純電動賽車與燃油賽車各自的特點;按照驅(qū)動電機的數(shù)量,對比了純電動賽車三種不同驅(qū)動形式的特點;介紹了純電動賽車驅(qū)動電機及電機控制技術(shù)、動力電池及電池管理系統(tǒng)這些關(guān)鍵技術(shù);根據(jù)賽車動力性目標與續(xù)駛里程要求為賽車匹配了驅(qū)動電機、傳動系統(tǒng)參數(shù),以及動力電池;使用Optimum Lap軟件對襄陽夢想方程式賽道進行建模,建立了FSAE工況;使用CRUISE汽車動力學仿真軟件建立賽車整車模型,對賽車最大速度、75m直線加速、FSAE工況,賽車動力性能與競賽項目進行仿真分析,仿真結(jié)果顯示賽車動力匹配滿足設(shè)計目標;完成賽車整車搭建。根據(jù)方程式競賽項目要求和相關(guān)測試標準,對賽車最高車速、75m直線加速以及續(xù)駛里程耐久性進行了實車試驗。測試數(shù)據(jù)與設(shè)計目標對比分析,最高車速測試數(shù)據(jù)為145km/h滿足設(shè)計要求;75m直線加速時間測試數(shù)據(jù)比設(shè)計目標長出0.53s,差距主要來自賽車加工誤差;續(xù)駛里程耐久試驗,賽車可以完成22km的設(shè)計目標。
[Abstract]:Formula SAE (FSAE) is to develop automobile industry technical personnel and other mechanical technical personnel for the purpose of providing the practice of the theory of knowledge of the use of.2010 Formula SAE competition was officially settled in China for college students from the university students formula car contest in Chinese development, 2013 China formula car series and the pure electric car into the race, now Chinese Formula SAE Engineering University Chinese college students has become one of the most widely participate in competitions. Power system is the core of the car, the car determines the dynamic performance and competitive strength, directly affect the outcome of the game, so the car matching of power system is crucial. This paper takes Chang'an University pure electric car - hunting power as the research object, on the basis of the equation of racing competition project into action. The matching principle of pure electric car, from the space structure, mechanical structure, the four aspects of driving system and electrical system and analyzed the difference formula for commercial vehicles, pure electric cars and fuel car characteristics; according to the number of driving motor, compared to the pure electric car three different drive form the pure electric car characteristics; driving motor and motor control technology, power battery and battery management system the key technology; according to the dynamic target and the car mileage requirements, the drive motor for the car transmission system parameters, and power battery; the Xiangyang dream Formula 1 track is modeled using the Optimum Lap software, established FSAE the establishment of the car condition; the vehicle model used in the dynamic simulation software CRUISE for racing cars, the maximum speed, 75m linear accelerator, FSAE condition, dynamic performance and competitive racing Simulation analysis of events, the simulation results show that the car power matching meets the design objectives; complete racing vehicle built. According to the formula and competition project requirements and related testing standards, the car top speed, 75m linear acceleration and mileage of the vehicle durability test. The comparative analysis of the test data and the design goal, top speed test data for 145km/h to meet the design requirements; 75m linear acceleration time test data of 0.53s longer than the design target, mainly from the gap between car machining error; mileage durability test, the car can complete the design goal of 22km.
