A Study on Pressure, Flow Fluctuation and Noise in the Cylinder of Swash Plate Type Axial Piston Pump

사판식 피스톤형 유압펌프에서의 실린더내 압력, 맥동, 소음에 관한 실험적 연구

Noise reduction for hydraulic pump is strongly demanded in the market with its efficiency and durability. In order to meet this demand, it is necessary to reveal mechanism for noise and relationship between the important factors. In this paper, mathematical model for cylinder pressure which is primary reason of pulsation and sound noise were established, and examined its pressure profile by simulation. Also, the valve plate of three kind types are manufactured and tested for piston pressure, pressure pulsation, and sound power level based on the tentative standard which is officially recognized.
