Analysis and Improvement on Noise of Electro-hydraulic Steering System for Pure Electric Buses
QI Ying,WANG Haoyu,LI Junqiang
Abstract: Aiming at the noise source,type,and transmission path of the electro-hydraulic steering systemfor 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 subjectiveevaluation,which finally reduces the noise of the electro-hydraulic steering system and improves the ridecomfort of the whole vehicle.
Key words: pure electric bus; electro-hydraulic steering; noise analysis and improvement
