高速车辆的气流噪声是现代科技高度发达而产生的新问题。本文以气流声学和涡动力学为基础,分析了高速车辆气流噪声的主要产生机理,并对气流噪声的计算方法以及车外脉动压力场的计算理论进行了初步探讨。
Airflow noise of high-speed vehicles is a new problem arising from the highly developed modern science and technology. Based on airflow acoustics and eddy dynamics, this paper analyzes the main mechanism of airflow noise in high-speed vehicles, and discusses the calculation method of airflow noise and the calculation theory of pulsating pressure field outside the vehicle.
