摘要/Abstract

摘要：

高速列车转向架区域为其主要气动噪声源之一，迄今为止较难描述高速列车气动噪声源特征，鲜有有效的声源识别方法。利用高速列车转向架区域以偶极子声源为主的声源特征，将气动声源等效为无数个球形声源的集合，基于声辐射与声源，声源与流场物理量之间的关系，结合流体数值仿真，建立高速列车偶极子声源识别方法，并聚焦头车转向架区域进行声源识别。同时，以涡声理论为基础，建立偶极子声源强度和流场多物理量的关系，分析流场产生声源的本质。研究表明，偶极子声源集中的位置多为迎风侧气流与壁面发生激烈作用的位置，气流与壁面发生撞击与分离是产生偶极子声源的主要原因，且在该区域涡量的变化对偶极声源强度影响最大，在不同区域，不同方向的涡量分量在起主导作用。

Abstract:

The bogie area of high-speed trains is one of main sources for aerodynamic noise. So far， it is difficult to describe the characteristics of aerodynamic noise sources of high-speed trains， there are few effective sound source identification methods. Using the characteristics of the sound source dominated by dipole sound sources in the high-speed train bogie area， the aerodynamic sound source is equivalent to a collection of countless spherical sound sources. Based on the relationship between sound radiation and sound source， sound source and flow field physical quantities according to the relationship， combined with the fluid numerical simulation， a method for identifying the sound source of the high-speed train dipole was established， and the sound source was identified by focusing on the bogie area of the lead car. At the same time， based on the vortex sound theory， the relationship between the intensity of the dipole sound source and the multi-physics of the flow field was established， and the essence of the sound source generated by the flow field was analyzed. The research shows that the concentrated position of the dipole sound source is mostly the position where the windward side airflow and the wall surface strongly interact， and the collision and separation of the airflow and the wall surface are the main reasons for the generation of the dipole sound source， and the change of vorticity in this area is dual. The intensity of the polar sound source has the greatest influence， and in different regions， the vorticity components in different directions play a leading role.

Key words: vehicle engineering, high-speed train, bogie, dipole sound source, numerical simulation, vortex sound equation
