摘　　要： 针对厢式运输车厢体表面减阻问题,提出一种基于气膜减阻的厢式运输车厢体风阻减阻方法。设计气膜发生器和可变风速测阻装置,分别以安装和未安装该气膜发生器的厢式运输车模型为试验研究对象,在可变风速测阻装置中进行风阻测试。结果表明,气膜发生器能够起到一定的减阻效果,从而验证了气膜减阻方法用于厢式运输车厢体减阻是可行的。 Aimed at the problem of drag reduction on the surface of van body, the method of air film drag reduction was proposed to reduce the wind resistance of van body. The air film generator and the wind resistance test device were designed, the wind resistance tests were performed for the vans with and without the air film generator respectively in the wind resistance test device. The test result shows that the air film generator has a good effect of drag reduction, and it verifies that the air film drag reduction method can be used to reduce the wind resistance of van body.
