Acoustic Property of Structure-Acoustic Coupling System for Rail Car

XIE Su-ming,FU Ya-lan,WANG Yue-dong,ZHAO Wen-zhong(School of Traffic and Transportation Engineering,Dalian Jiaotong University,Dalian 116028,China)  
As noise level inside a passenger car is one of the important characteristics to determine vehicle quantity,considering the relationship between structure vibration and acoustic,a model of acoustic-structure coupling system for passenger car is constructed,and the mode and harmonic analysis for the car structure model,air cavity model and acoustic-structure coupling model are performed.The acoustic field distribution of the interior car at low frequency is discussed.The results can be referred for further study on the noise radiation control.
