Parameters Matching and Optimization for Multiple Power Sources of Electric Drive Armored Vehicles

为提高电传动装甲车辆的动力性和燃油经济性,根据极限行驶工况确定了各动力源参数可行域。依据某重型车辆循环行驶工况,选取5组不同混合度的参数匹配方案,分别在Cruise整车模型上进行仿真试验,确定了等效燃油消耗量。结果表明:匹配与优化后的多动力源参数匹配方案能够满足车辆动力性要求,提高燃油经济性。

To improve the mobility and fuel economy of electric drive armored vehicles,the constraint range of multiple power sources is confirmed according to extreme drive conditions. Under the heavy vehicle driving cycle,5 groups of parameters matching schemes are selected with different mixing ratios. The scheme with lowest fuel consumption is determined by simulation experiment based on Cruise vehicle model. The result of simulation demonstrates that the optimized parameters matching schemes of multiple power sources can meet the requirements of vehicles' driving performance and improve the fuel economy.
