列车运行噪声是高架线路声屏障、地下线路活塞风井消声器的设计输入条件。通过列车运行噪声影响因素分析,建立了列车运行噪声估算的简化模型,推导了城市轨道交通列车在不同运行条件、不同运行速度时的运行噪声估算方法。
The train running noise is the design input condition of overhead line sound barrier and underground line piston shaft muffler. Based on the analysis of influencing factors of train running noise, a simplified model of train running noise estimation was established and the running noise estimation method of urban rail transit trains under different operating conditions and operating speeds was derived.
