轨道车辆直流牵引电机噪声的分析与研究

Analysis and Research of Noise of DC Traction Motor for City Railcars

本文在城市轨道车辆牵引电机噪声测试的基础上,分析了牵引电机噪声的产生机理和频率分布以及对室内外环境的影响和传播途径。最后提出了牵引电机的降噪措施。

Based upon testing the noise of traction motor for city railcars,analyzes the mechanism of produced noise of traction-motor,the frequency distribution,the influence on indoor and outdoor environment,and the transmitting way.At last,proposes the measures reducing the noise of traction motors.
