【摘要】：动力系统是方程式赛车设计的关键,是取得优异动态项目成绩的保证。目前我校车队及国内其他大部分高校车队一直采用的是单电机动力系统。方程式赛车采用双电机动力系统,减少了差速器等传动系部件,有利于赛车紧凑布置,而且提高动力系统传动效率,但是采用双电机动力系统其控制难度增大。本文依托广东工业大学电动方程式赛车的多年研发技术与经验的积累,对方程式赛车双电机动力系统进行了初步研究。本文主要在双电机电动赛车动力学分析和行驶控制策略、双电机动力系统的理论参数设计和性能仿真验证方面展开研究工作,具体内容如下：首先,分析电动方程式赛车动力系统结构和动力系统布置需考虑的几个因素,在对目前电动汽车动力系统布置方案进行分析和比较各种方案优缺点的基础上,提出双电机动力系统布置方案。对双电机方程式赛车直线行驶和转弯行驶进行动力学研究,并对电机同步控制方法和电子差速控制方法进行研究,提出同步控制和差速控制的协调控制策略。其次,分析中国大学生电动方程式汽车大赛的动态赛项目,参考国内外赛车数据及我校车队往届赛车研发经验,确定方程式赛车整车主要参数及性能指标,然后对方程式赛车双电机动力系统的电机、电池等部件进行理论上的参数设计计算和匹配。最后,在Cruise汽车仿真软件平台建立双电机方程式赛车仿真模型,设定计算任务,并根据往届比赛数据建立赛道工况,对方程式赛车的动力性和经济性进行仿真分析,结果表明满足方程式赛车预期确定的性能指标,验证了双电机动力系统的参数设计和仿真模型的合理性。
[Abstract]:The power system is the key to the design of a Formula car, It is the guarantee of excellent dynamic project achievement. At present, the motorcade of our school and most other colleges and universities teams in our country have been using single motor power system. The formula racing car adopts double motor power system, which reduces the transmission system parts such as differential, etc. It is beneficial to the compact arrangement of the racing car and improve the transmission efficiency of the power system, but it is more difficult to control with the dual motor power system. This paper relies on the accumulation of many years'R & D technology and experience of the electric equation racing car of Guangdong University of Technology. In this paper, the dynamic analysis and driving control strategy of double-motor motor race car, the theoretical parameter design and performance simulation verification of double-motor motor racing power system are studied. The specific contents are as follows: firstly, this paper analyzes the power system structure and power system layout of electric equation racing car, and analyzes and compares the advantages and disadvantages of various power system layout schemes for electric vehicles. This paper puts forward the layout scheme of double motor power system, studies the dynamics of straight line driving and turning driving of double motor equation racing car, and studies the synchronous control method and electronic differential speed control method of the motor. The coordinated control strategy of synchronous control and differential control is put forward. Secondly, the dynamic events of Chinese University students' Electric Formula car Competition are analyzed, and the research and development experience of our school's previous racing teams is referred to the domestic and foreign racing data. The main parameters and performance indexes of the whole car are determined, and then the parameters of the motor, battery and other components of the power system of the double motor in the equation racing are calculated and matched theoretically. In the Cruise vehicle simulation software platform, the simulation model of double-motor equation racing is established, the calculation task is set up, and the track working condition is established according to the previous race data, and the dynamic and economic performance of the equation racing is simulated and analyzed. The results show that the performance index of the equation racing car is satisfied, and the rationality of the parameter design and simulation model of the double-motor power system is verified.
