利用声激励技术降低汽车车身阻力的实验研究

Experiment Investigation on Reducing Automobile Body Drag by Acoustic Excitation

本文利用内部声激励技术,在风洞中对某厢式客车车身模型进行空气阻力系数的测试。结果表明:内部声激励能够明显地降低车身模型的空气阻力系数。

The aerodynamic drag coefficient of a bus body model is measured in the wind tunnel with the acoustic excitation technique applied. It is shown that the technique can obviously reduce the aerodynamic drag coefficient of the model.
