摘要 本文首先简要地分析了声激励减阻机理。然后,针对类似桑塔纳车身的模型采用了声激励的方法进行了减低空气阻力的研究,得出了声激励参数、方式和减阻效果的关系,并且对此进行了一定的分析,表明利用声激励方法可以进一步降低此类车身的空气阻力。 The mechanism of reducing aerodynamic drag by acoustic excitation was briefly analyzed. Then a study of reducing drag by acoustic excitation was carried out on a Santana body model. The relations among the parameters, such as acoustic frequency, intensity, location and drag reduction rates have been obtained. It is shown that this technique can reduce aerodynamic drag of passenger car.
