摘要: 为了评估前围局部造型参数对大客车气动特性的影响,结合Ahmed模型及其风洞试验数据,论证数值模拟方案的有效性;针对12 m大客车模型评估前围局部特征,包括前顶弧、前侧弧以及前扰流板对大客车气动阻力和升力系数的影响规律。研究表明:前顶弧半径、前侧弧半径以及前扰流板角度增加时,客车的气动阻力系数降低,气动升力系数升高;对气动阻力影响程度的大小依次为:前侧弧半径>前顶弧半径>前扰流板角度,而对气动升力影响无显著差异。

Abstract: In order to assess the effect of styling parameters of front wall on the aerodynamic characteristic of a coach, The validity of the numerical simulation was verified based on Ahmed model and the relevant wind tunnel testing. According to a 12 m coach model, the local features of front wall were evaluated, which included the influence rule of arc radius of front roof, arc radius of front side and front spoiler angle on the drag factor and lift factor of a coach. The results indicate that the drag factor and lift factor of the coach respectively reduce and go up when arc radius of front roof, arc radius of front side and front spoiler angle increase; the influential sequence of the above factors on the drag factor is arc radius of front side > arc radius of front roof > front spoiler angle, whereas there is no significant difference on the effect of the lift factor.

Key words: vehicle engineering, arc radius of front roof, arc radius of front side, front spoiler angle, aerodynamic characteristics, coach
