摘要:

本文旨在对某重型半挂牵引车燃油经济性的改善进行研究。首先,对后视镜进行了优化,风洞试验结果风阻系数降低了0.012。接着,利用遗传算法对传动系统参数进行优化。并通过改进电控硅油风扇的控制策略,降低了发动机附件的功率消耗,Simulink/Crusie联合仿真和转鼓试验台测试的结果:C-WTVC循环工况油耗分别降低了1.7%和2%。最后,实车道路试验结果表明,优化后的车辆百公里综合油耗降低1.14 L,相当于3%。

Abstract:

This paper aims to study the improvement of the fuel economy of a heavy semi-trailer tractor. Firstly, an optimization is conducted on rearview mirror with a wind tunnel test result of a 0.012 reduction in drag factor. Then the parameters of transmission system are optimized and the control strategy of electronically controlled silicone oil fan is improved, resulting in a reduction in the power consumption of engine accessories, the results of Simulink/ Crusie joint-simulation and chassis dynamometer test show a 1.7% and 2% reduction in fuel consumption of C-WTVC cycle respectively. Finally, a real vehicle road test is carried out with a result indicating that the comprehensive fuel consumption of the optimized vehicle lowers by 1.14 L/100 km, corresponding to a reduction of 3%.

Key words: heavy semi-trailer tractor, fuel economy, optimization
