纯电动客车电动液压转向系统噪声分析与改进

Analysis and Improvement on Noise of Electro-hydraulic Steering System for Pure Electric Buses

针对纯电动客车电动液压转向系统的噪声来源、种类、传播途径,通过噪声产生机理分析,进行试验研究和效果验证,采用客观数据与主观评价相结合的分析方法,最终降低电动液压转向系统噪声,提升整车乘坐舒适性。

Aiming at the noise source,type,and transmission path of the electro-hydraulic steering system for pure electric buses,this paper carries out experimental research and effect verification through the analy-sis of the noise generation mechanism,adopts the analysis method combining objective data and subjective evaluation,which finally reduces the noise of the electro-hydraulic steering system and improves the ride comfort of the whole vehicle.
