摘　　要：摩托车空气动力学特性对摩托车的动力性、经济性和操作稳定性有直接影响。由于国内没有摩托车专用风洞,道路滑行试验无法适用于所有车型,所以在一款新型巡航车造型开发阶段,采用空气动力学仿真方法分析实车模型的空气动力学特性,在此基础上指导多个部件优化设计,并对优化后提供的两个挡风板安装方案分别进行了整车仿真分析。仿真结果显示,优化后的两方案整车阻力系数Cd值均降低,两挡风板安装方案的空气动力学性能对比为进一步选型提供了参考依据。The aerodynamic characteristics of motorcycle influent the power performance,fuel economy and operation stability of motorcycles directly.Considering the absence of special wind tunnel for motorcycles in the domestic and road coasting test doing not apply to all types of motorcycle,aerodynamic simulation method was applied in the development process of a new touring styling by analyzing the aerodynamic characteristics of real vehicle model.Basing on that,the optimization design was made and then simulations were made respectively with two windscreen installation angles provided.The simulation results show that drag coefficient Cdis reduced by the optimization scheme and the aerodynamic characteristics comparison between the two installation schemes provide the reference for further style selection.
