摘要
在气动汽车动力系统性能优化的研究中,为了提高气动汽车的车速、爬坡度、加速时间和续驶里程等主要性能,验证气动汽车在实际应用中的可行性,建立气动汽车的动力传动系统的数学模型,在matlab中进行仿真计算。对气动汽车不同换挡时刻下的车速、加速度、耗气量对比分析,得到某款气动汽车的最高车速为72.1774km/h,最大爬坡度18.2%,原地一档起步连续换挡加速到70km/h的加速时间为65.6102s,40km/h匀速行驶的理论里程为108.1km。仿真结果符合国标对小汽车动力性的要求,表明气动汽车成为城市代步车是完全可行的,为以后研究气动汽车的整车性能提供指导价值。
Research the main performance of pneumatic vehicle, including maximum speed, gradeability, accel- erating ability and driving mileage and so on. In this paper, a mathematical model of the pneumatic automobile power transmission system was established and calculated using Matlab to prove that the pneumatic vehicle is feasible in ap- plications. Comparation of speed, acceleration and air consumption under different moments for speed shift can get the results. The results of the pneumatic models are that the maximum speed is 72. 1774km/h, the maximum grad- ability is 18.2%, a continuous shift speed to accelerate to 70km/h＇ s acceleration time is 50 seconds and driving at theory mileage of 108. lkm with constant speed 40km/h. The simulation results in line with the national standard for car power requirements. It indicates that aerodynamic car becoming a city scooter was entirely feasible, and provides a guidance for future research in the whole vehicle performance of aerodynamic car.
