城轨车辆车内噪声水平多工况影响因素分析
摘要
Abstract
The main noise source of urban rail vehicles is wheel-rail noise,which is a systematic problem related to vehicle-track coupling and wheel-rail relationship.Under tunnel operating conditions,the noise forms a reverberation field and transmits into the vehicle through transmission.At the same time,the sealing performance of urban rail vehicles is poor,resulting in the noise in the tunnel being 8～10 dB higher than that under open line operating conditions,seriously affecting passenger comfort.Based on the measured results of urban rail vehicle lines in China,the influence of wheel-rail roughness,track type,track attenuation,open line and tunnel on the noise level in the vehicle is quantitatively analyzed.On the basis of the analysis,some suggestions on the noise control of urban rail vehicles are put forward,which is convenient for the subsequent vehicle and route design and improves the ride comfort to the greatest extent.关键词
