Division and Contribution Analysis of High-speed railway Noise Sources
摘要
Abstract
Division and contribution analysis of high-speed railway noise sources are important for noise control. Locations and amplitudes of high-speed railway noise sources are determined through noise identification field tests. The sources are divided by height into wheel/track area, lower part of vehicle, upper part of vehicle, pantograph-catenary area and bridge area. For further analysis, the upper part of vehicle is divided in the direction of the line into head area and non-head area, and pantograph-catenary area is divided into pantograph area and catenary area. The noise contribution of each area is studied in terms of the total radiation power in each source area. Calculation results show that the noises in wheel/track area and the lower part of vehicle make up 48% and 25% separately, amount to 73% of the total, and dominate high-speed railway radiation noise.关键词
