客车模型空气动力学特性优化的研究

Research on Optimization for Aerodynamic Characteristics of A Bus Model

应用自行开发的三维流动数值模拟计算软件对一大客车模型的空气动力学特性进行了计算分析,并初步尝试通过“数值试验”比较不同设计方案以达到优化客车模型外形的目的。研究表明,应用计算流体力学方法优化车辆外形设计以提高其空气动力学特性,是提高车辆性能,缩短开发周期的有效途径之一。

With 3-D flow numerical simulation software the aerodynamic characteristics of a bus model is analyzed. In order to optimize the model contour some design conceptions are compared each other with 'numerical test'. The research has shown that, optimizing the vehicle's contour design with CFD method to raise its aerodynamic characteristics is the effective way to raise the vehicle performance and shorten the development time.
