摘要 为了进一步提高内藏门的密封性能,该文试验研究了地铁司机室内藏门密封性对司机室内噪声的影响。
试验研究结果表明:在隧道直线段运行条件下,司机座椅声压级满足标准要求,在曲线段因啸叫声而超出标准
限值;内藏门漏声主要来源于轮轨噪声;对司机室内藏门门框增加密封结构,可使隧道直线段在运行工况下司
机座椅处噪声降低 0.9 dB。最后,针对司机室内藏门门页后挡上门角漏声特征,提出了进一步的降噪措施。

Abstract In order to further improve the sealing performance of the cab sliding door, this paper experimen-
tally studied the sealing performance of the cab sliding door of the metro vehicle on the sound pressure level
inside the cab. Experimental results show that the sound pressure level of the driver’s seat is less than the
standard value in straight line under tunnel condition, and the results exceed the standard value in the curved
lines due to the howling. It is shown that the main noise source of the cab leakage is from the rolling noise.
The sound pressure level at the driver’s seat is reduced by 0.9 dB through extending the sealing strip on the
top of the front door frame in the straight lines under tunnel condition. Finally, the noise control solutions
are proposed to further improve the sealing performance of the sliding door on the top corner of the back door
frame.
