【摘要】：分析纯电动公交车能耗经济性是一项复杂的工程,并且纯电动公交车在实际运行过程中实际运行参数具有随机性和不确定性。因此除了驱动电机的类型、电池的参数、传动系统匹配程度等传统因素对纯电动车耗能经济性影响之外,利用区间数学的分析方法对车速、载质量、道路坡度和滚阻系数等运行参数的单一因素的波动对纯电动公交车能耗的影响程度进行分析,证实了纯电动公交车能耗随运行参数波动产生变化的影响,进而采用极差分析法从宏观对相应实际运行参数进行敏感性分析,其结果表明:道路阻力系数的波动对纯电动公交车的能耗影响最大,能耗随着承载质量的增加而增大,而速度的波动对公交车的能耗影响较小。
[Abstract]:It is a complex project to analyze the energy consumption economy of pure electric bus, and the actual operation parameters of pure electric bus are randomness and uncertainty in the actual operation process, so besides the type of driving motor, the parameters of battery, In addition to the influence of traditional factors, such as the matching degree of transmission system, on the energy consumption economy of pure electric vehicles, the speed and load quality of pure electric vehicles are analyzed by the method of interval mathematics. The influence degree of single factor such as road slope and rolling resistance coefficient on the energy consumption of pure electric bus is analyzed. It is proved that the energy consumption of pure electric bus varies with the fluctuation of operation parameters. Then the sensitivity analysis of the actual operation parameters is carried out by using the range analysis method. The results show that the fluctuation of the road resistance coefficient has the greatest influence on the energy consumption of the pure electric bus, and the energy consumption increases with the increase of the bearing mass. The fluctuation of speed has little effect on the energy consumption of buses.
