摘　　要：为提高电动方程式赛车的动力性和经济性,根据赛车实际参数在汽车仿真软件AVL-Cruise中和模拟驾驶软件Assetto Corsa中建立模型。通过模拟驾驶,采集赛车直线加速赛和耐久赛的近似工况。直线加速赛的时间和耐久赛的耗电量能够通过仿真计算获得。设计赛车跑动试验,实测结果与仿真结果的误差百分比小于0.5%,验证了模型的准确性。根据仿真结果优化动力总成的驱动电机功率、动力电池容量、总减速比等参数并进行多因素仿真分析,最优方案使赛车在动力性上提升了11.1%,经济性提升了9.4%。In order to improve the power performance and economy of the electric formula racing car,the model was established in AVL-Cruise and Assetto Corsa according to the parameters of the racing car.The approximate working conditions of the straight-line acceleration and the endurance were collected through the simulation of driving.The time of the straight-line acceleration and the power consumption of the endurance were obtained through the simulation calculation.The running test of the racing car was designed,and the error percentage between the measured results and the simulation results is less than0.5%,which verifies the accuracy of the model.According to the simulation results,the driving motor power,battery capacity,total deceleration ratio and other parameters of the powertrain were optimized and the multi-factor simulation analysis was carried out.The optimal scheme improves the power performance of the car by 11.1%and economy by 9.4%.
