摘要

针对目前各型机车制动电阻装置在设计时均未考虑降噪要求的情况，简要介绍机车制动电阻装置噪声研究及控制的背景及现状，通过对电阻装置近场表面声功率及其频谱的分析，识别出制动电阻装置主要噪声和频率构成，提出制动电阻装置降噪方案。

Abstract

According to the condition that brake resistor of locomotive no considering noise reduction requirements, background and status of noise research and control on the locomotive braking resistor devices were introduced. By analyzing the near-field surface sound power and spectrum of the resistor device, the main noise and frequency composition could be identified, and further the noise reduction approaches were proposed for the braking resistor devices.
