Study on performance simulation of extended-range electric sanitation vehicle

该文以增程式电动环卫车为研究对象,以整车基本参数及性能设计目标为限制条件,运用汽车理论相关知识对驱动电机、动力电池和增程器等关键部件的功率进行匹配计算。利用Advisor仿真软件建立关键部件模型,并采用NEDC循环工况进行模拟仿真。仿真结果表明,在满足动力性和燃油经济性的基础上,最高时速可达87 km/h,0~50 km/h加速时间小于15 s,电动环卫车能保持在最佳效率区域运行,且满足续驶里程的设计需求。

The extended-range electric sanitation vehicle is studied in this paper. Taking the fundamental parameters of the whole vehicle and the performance design objective as the constraint conditions,the power matching calculations are performed for the key components such as the drive motor,power battery,and range extender by using the related knowledge of automobile theory. The Advisor simulation software is used to build the models of key components. The NEDC cyclic working condition is used to perform analog simulation. The simulation results show that on the basis of meeting the dynamic and fuel economy requirements,the maximum speed of the electric sanitation vehicle reaches 87 km/h,and the acceleration time of 0~50 km/h is less than 15 seconds;the electric sanitation vehicle can keep operation in the best efficiency zone and meet the design requirement of endurance mileage.
