摘　　要：动力性和燃油经济性是车辆性能的重要评价指标。本文利用GT-SUITEmp建立了整车仿真模型,进行动力性、经济性计算。基于此模型,本文在原有主减速比的基础上改变了主减速比,仿真结果显示,优化后的主减速比,在NEDC循环工况下油耗有所降低。Dynamics and fuel economy are two important evaluation indexes of the vehicle perfornance. The vehicle model was established by GT-SUITEmp in this paper, which was calculated the vehicle performance and fuel consumption. Based on this model, We improved the fuel economy through optimizing the final ratio. The simulation results showed that the NEDC fuel consumption reduced owing to the optimization of the final ratio.

关 键 词：动力性 经济性 GT-SUITE 主减速比优化
