摘　　要：发动机驱动风扇在整车上产生的噪声主要在高转速的工况,风扇高速旋转产生气流噪声,通过辐射传递到驾驶室。主要通过研究某轻卡车型上使用的硅油离合器风扇在不同风扇转速、不同风扇宽度伸入到护风圈的深度关系来研究降低风扇噪声的方法,采用了理论分析及实车验证相结合的方法。The noise from the engine drive fan is mainly generated by the fan blade when operated in high speed,the air flow noise cause by the fan rotation will radiating to driving cab.The method reducing engine drive fan noise of light duty truck was studied through studying the influence of fan speed and fan coverage(percent)on driving cab fan noise of light duty truck,adopting the theory analysis and vehicle verification method.

关 键 词：发动机驱动风扇 噪声 辐射
