【Abstract】 The large undulation of pressure at the large-scale hydraulic pump station is usually caused by the pulsating of flow.It’s one of essential causes to produce noise in the hydraulic system.The vibration cause and the methods of reducing vibrationin the vane pump are clarified by means of a large number of the test data and measuring curves,and applying the automatic control theory and fluid mechanics law.This type of resonant absorber is proved to greatly reduce the fluid vibration in the hydraulic system which is caused by the hydraulic pump,and little power is lost. Therefore,it is suitable to eliminate noise and reduce vibration in the various hydraulic systems.更多还原
