摘要 文中阐述了气动噪声数值分析的两个步骤,即采用大涡模拟(LES)计算汽车外部瞬态流场和采用FW-H声学模型预测其噪声特性。最后介绍了该数值仿真方法在汽车设计中的应用以及降低气动噪声的措施。 In this paper, two steps of aerodynamic noise analysis are expounded, i. e.. , the transient exterior flow field is calculated by large eddy simulation （LES） and then the noise characteristics are forecasted using FW-H acoustic model. Finally some application examples of numerical simulation in vehicle design are presented with the measures for reducing aerodynamic noise given.
