가변 용량형 유압 베인 펌프의 소음과 진동에 관한 비교분석

Abstract

Engine lubrication is closely related to the durability and the car’s fuel economy. Variable displacement vane pump is applied to increasing the engine performance and energy efficiency. However the noise problems are caused by the variable displacement vane pump of the high speed engine. In this paper, Noise and vibration experiment are performed on test machine with isolating other noise source of the engine and compare the trends of exciting and harmonic components to provide a basis for identifying the causes of noise in variable displacement vane pump.
