汽车燃油泵噪音优化方案研究

汽车怠速工况下,乘员舱内一般可以感知燃油泵工作产生的"嗡嗡音"。文章针对这项问题,从噪音源和传递路径分析燃油泵工作噪音的产生、传递、感知的整体过程,同时在源和路径上寻找降低噪音的措施。在满足整车供油需求的前提下,降低怠速时乘员舱燃油泵工作噪音,提升汽车舒适性。

Study on Noise Optimization Scheme of Automobile Fuel Pump

During automobile idling condition, passengers can generally sense "wengweng" in passenger compartment, which generated by the work of the fuel pump. Aiming at this problem, this paper analyzes the whole process of generating, transmitting and perceiving the operating noise of fuel pump from the noise source and transmission path, at the same time looks for measures to reduce the noise on the source and the path. On the premise of meeting the fuel supply demand of the vehicle, reduce the noise of fuel pump in crew cabin during idle, and improve the comfort of the vehicle.
