摘　　要：轨道车辆特别是高速列车随着车辆运行速度的不断提高,车内噪声会显著增大。相比于隔声吸声等噪声被动控制技术,噪声主动控制技术具有轻量化、低频降噪效果好的优点。介绍了噪声主动控制技术和轨道车辆噪声源特点,对噪声主动控制技术在轨道车辆噪声控制国内外研究现状进行了综述,简要分析了噪声主动控制中次级声源和误差传感器布放策略和FXLMS控制算法。对噪声主动控制技术用于轨道车辆噪声控制的发展方向进行了初步讨论。Interior noise of railway vehicle especially high-speed train increases with vehicle＇s speed increasing. Compared with passive noise control such as sound insulation and absorption, active noise control （ANC） has many advantages such as lightweight and effective for attenuating with low frequency noise. Active noise control technology and noise source characteristics of railway vehicle was introduced briefly. Present research status of ANC technology for decreasing railway vehicle noise at home and abroad was reviewed. A brief analysis about arrangement strategy of secondly sound resource and error sensors and FXLMS control algorithm was provided. Development trend about ANC technology for decreasing interior noise of railway vehicle was oreliminarv discussed.
