摘要

摘要: LNG汽车具有清洁、高效、经济的特点。以某LNG牵引车为目标车型,应用CRUISE软件建立LNG牵引汽车仿真模型,对其动力性和经济性进行了分析。然后应用正交试验对其变速器和主减速器速比进行匹配优化选出最优匹配方案,得到优化方案。与原车型方案相比,整车爬坡性能、加速性能略有降低,但最高车速提升了10.08%,重型载货车六工况燃气消耗降低了17.72%,经济性能有较大改善。

Abstract: Liquefied Natural Gas (LNG) vehicle has been rapidly developed due to its clean and economical characteristics. In this paper, taking a LNG towing vehicle as the target model, the simulation model for LNG truck has established and the power performance and economy performance have been analyzed via AVL CRUISE software. The optimal matching scheme is obtained by orthogonal test for factors of gearbox and final drive speed ratio. The results shows that, comparing with original scheme, despite the climbing and acceleration performance are slightly decreased, the maximum speed of the truck is increased by 10.08%, the fuel consumption is improved by 17.72% and the economy performance is significantly improved, providing reference for the optimization design of powertrain for LNG vehicle.
