摘　　要：以柴油发动机驱动的30 t矿用自卸车为原型,设计一套由发动机和电动机共同驱动的混合动力系统。根据矿区对自卸车动力性的要求,确定混合动力自卸车的驱动形式和性能指标,并对发动机、电机及动力电池等关键部件进行参数匹配计算。基于作业工况对动力的需求,设计混合动力系统的工作模式和动力分配方案。对原型车和混合动力自卸车分别进行循环工况仿真和最大爬坡度仿真。仿真结果表明,所设计的混合动力自卸车满足各项性能指标要求,油耗较原型车显著降低,改善了燃油经济性。Taking a 30-t mining dumper driven by a diesel engine as the prototype,a set of hybrid powertrain system driven by an engine and an electric motor is designed.According to the requirements of the mining area on the power of dumpers,the drive form and performance indexes of the hybrid dumper are determined,and the parameter matching calculations are carried out for the key components such as the engine,the electric motor and the traction battery.Based on the demand for power in operating conditions,the working mode and power distribution scheme of the hybrid powertrain system are designed.Cyclic working condition simulation and maximum climbing slope simulation are performed on the prototype and hybrid dumper respectively.The simulation results show that the designed hybrid dumper meets the requirements of each performance index,significantly reduces the fuel consumption compared with the prototype and improves the fuel economy.
