摘　　要：为评价客车的气动特性,针对一量产大客车模型进行不同前围造型和尾翼方案的风洞试验对比研究。结果表明,前围倾角加大,气动阻力系数变小;侧向力系数随横摆角增加而大幅增加;加装合理尾翼可减少气动阻力。In order to evaluate the aerodynamic characteristics of coaches, the authors take the wind tunnel tests for different front walls modeling and tail wings of a product big coach. The research results indicate that the aerodynamic drag coefficient decreases when the inclination angel of the front wall increases, the lateral force coefficient increases rapidly when the yawing angle increases, and the aerodynamic drag decreases when a reasonable tail wing is installed.
