Sensitivity analysis of fluid vibration system for high speed and high pressure axial piston pump

摘要

The continuous pursuit of high power to weight ratio of hydraulic system promotes the development of axial piston pump to high speed and high pressure, and puts forward more urgent demand for fluid piston vibration control strategy of axial piston pump. In this paper, the transfer path analysis method is used to study the transfer characteristics of fluid vibration transmission path of different axial piston pumps. The analysis of the vibration transfer path directly reflects the difference in the transmission capacity of different transmission paths. The proposed method of transmission path analysis can provide more pertinent guidance for the vibration reduction and noise reduction of axial piston pump.
