摘要: 地铁司机室的声学环境对于司机的身心健康以及行车安全至关重要。司机室处于在转向架上方,其噪声主要来源于轮轨噪声,而钢轨波磨是地铁中常见的问题,严重的波磨会显著增大轮轨噪声,从而影响司机室的声学环境。众所周知波磨与车内噪声存在正相关的定性关系,但两者之间的定量关系尚不明确。因此深入地研究钢轨波磨与司机室车内噪声之间的关系,对司机室车内噪声控制至关重要。本文采取了现场试验与仿真计算相结合的研究方法,分析了有无波磨对司机室车内噪声的影响,以及司机室车内噪声与钢轨波磨之间的定量关系。

Abstract: The acoustic environment of the metro cab is very important for driver's health and even traffic safety. The main source of the interior noise of the cab is the wheel/rail noise, since the location of the cab is just above the bogie. Furthermore, the serious rail corrugation is very common in the metro system, which will enhance the wheel/rail noise and have a great effect on interior noise of the cab. As we all know, there is a positive correlation between the interior noise and the rail corrugation, but the quantitative relation is unclear yet. So, it is of great significance for the interior noise control to have an insight in the relationship between interior noise and rail corrugation. A combination method of field test and simulation is adopted in this study to analyze the effect on interior noise caused by rail corrugation and the quantitative relation between them.

Key words: interior noise, metro cab, rail corrugation, wheel/rail noise
