摘　　要：影响客车外围流场空气动力学特性的因素较多,各个因素需要研究的水平也较多。应用正交试验设计方法确定模拟计算方案,不但可极大地降低计算分析工作量,还能得到较优方案。There are many elements which can impact aerodynamic character on the coach external flow field, and the different elements have different study levels. Using the orthogonal design method to fix the calculation program of simulation computation can not only greatly reduce the computation load, but also get the nearly optiomal plan.
