Identification of acoustical noise source for electric power steering motor using finite element method

摘要

Recently, electric power steering (EPS) systems have attracted much attention due to their advantages such as high fuel efficiency, tunability of steering feel, weight reduction of steering system, environmental friendliness, etc. [1-4]. However, vibroacoustic radiation noise occurs, which is not seen in hydraulic steering systems. The fundamental source of the vibroacoustic noise is considered to be from the electric motor.
