摘要
介绍了客车地板传播噪声的途径和衰减噪声的措施。设计了适用于２００ｋｍ／ｈ高速客车的浮筑地板结构，该结构具有较好的减振性能和隔声性能，是理想的高速客车用地板结构。
The noise propagation ways and noise abatment measures by the floor in passenger cars are described.The floating floor structure which is suitable to the 200km/h high speed passenger cars is designed.The structure has fairly good damping performance and noise insulation performance.It is an ideal floor structure for high speed passenger cars.
