摘要
通过对典型客车模型风洞试验过程、方法以及试验数据的分析介绍,给出了客车模型在60m/s风速时,气动阻力系数随横摆角的变化关系曲线,零横摆角时的表面压力分布。研究结论可为客车空动力学特性、客车的设计和选型提供参考。
In this paper, the procedure and methods of wind tunnel test for typical bus model are described, Under the condition of 60m/s, the data obtained from the test are shown in a figure, in which CD changes with different yaw angles. A figure for the surface pressure distribution at 0-deg yaw angle is also given,
