摘要：
Acoustic field visualization can more intuitively master the distribution characteristics of sound field and provide more information about sound field. Based on this, a visualization technique of acoustic field for high speed railway based on wave superposition method (WSM) of moving acoustic source is proposed, which aims to expose the distribution characteristics of radiated sound field by railway when high speed train passes through. Starting with the sound source configuration of high-speed railway as the train passes by, dipole sound source models are adopted to reconstruct wave superposition theory. By combining the least square method with genetic algorithm, the source strength and angle of direction are solved. The application program for radiated noise field visualization based on the superposition theory of moving source wave is developed by using atlab, and the program is applied to the study of the radiated noise field of high speed railway. Results show that the visualization technology for the radiated acoustic field of high speed railway based on wave superposition method is feasible. With Doppler correction, the reconstruction of railway radiated noise field is more accurate when the train passes by. The direction angle of a certain type of high-speed train radiated sound source is about 27° at the speed of 310 km • h-1, and the sound field is inclined upward; when the train passes through, the railway noise is mainly concentrated in the wheel-rail area, and the radiation noise attenuation in this area is slow. © 2020, Editorial Department of China Railway Science.
