铁路客车地板材料隔声性能有限元分析

Finite Element Analysis of Sound Insulation Property of Railway Passenger Car Floor

从提高铁路客车地板隔声性能出发,应用隔声原理和有限元理论,在隔声室内对客车地板材料进行降噪分析,其研究结果对铁路客车降噪设计具有一定参考价值。

With the increasing of the speed of the railway passenger cars, noise problem gains more attention. A successful design of sound insulation floor for noise reduction of the railway passenger cars is the key for solving the problem. To improve the sound insulation property of the railway passenger car floor, the finite element analysis for noise reduction of the car floor is carried out based on sound insulation principle. The result is of significance for noise reduction design of the railway passenger cars.
