摘要:
随着地铁列车运行速度的提高,车内噪声问题日益严重,文章针对地铁列车车体结构,进行部件隔声测试与优化,并通过车内噪声预测,研究各类组合方案的车体结构运用于 120 km/h 速度等级地铁列车时的降噪效果。研究表明,地板隔声量的提高对动态车内噪声的降低有积极作用。
Abstract:
With the increase of the speed of metro trains, the problem of interior noise is becoming more and more serious. The sound insulation test and optimization of components were carried out for the car body structure of metro train, and the noise reduction effect of the car body structure of various combination schemes when applied to the 120 km/h speed class metro train was studied through the prediction of the noise in the car. The research showed that the increase of floor sound insulation had a positive effect on the reduction of dynamic interior noise.
