Multi-factor Influence Analysis and Control Measures of Urban Rail Vehicle Noise
The noise level of urban rail vehicles has become one of the main concerns.The main noise source is wheel-rail noise,which is also affected by multiple factors such as vehicle-track coupling and multiple curve segments,re-sulting in an increase of 5～10 dB in noise during long-term operation,which seriously affects passenger comfort.Based on the research results of urban rail vehicle lines in China,the influence of track conditions,small curves,open lines and tunnels on the noise level in the vehicle is analyzed.On the basis of analysis,the corresponding control measures are put forward to guide the vehicle and route design and improve the passenger ride comfort.
