Abstract:

Based on some type of high-speed train, the different bogie area noise was tested and studied , which was one of the main noise sources of high-speed train in operation. Through the analogically test and analyze the noise characteristics in different bogies, it can be concluded that the main noise source in bogie areas of the intermediate trail car is wheel-rail noise at the speed level of 350km·h^-1 or below, the main noise source in bogie areas of the head and rear car is pneumatic noise, and the main noise source in bogie areas of the intermediate motor car is traction system noise. Furthermore, based on above results and some assumptions, the spectrum and contribution characteristics of major noise sources were studied and obtained for bogie areas of the head, rear and motor car. The research results can provide a basis and guidance for vibration and noise reduction of high-speed trains.

Key words:high-speed train;bogie area;wheel-rail noise;pneumatic noise;traction system noise;separation characteristics
