Abstract

Abstract: Aiming at the problem that air bubbles mix into hydraulic oil would affect fluid properties, and then would affect the flow characters of axial piston pump with concial cylinder block, according to the theoretical ananlysis, the generic submodel of the fluid properties and single piston/swash plate mechanism were developed by AMESet, and the simulation result verified the applicability of the fluid properties generic submodel. The model of whole pistion pump was developed by AMESim. The influences of air content in hydraulic oil and pistion dip angle on the flow characters of pistion pump were studied. The results show that with the increase of air content inhydraulic oil, the average flow will decrease, the efficiency of pump will decrease, and the flow pulsation amplitude and rate will increase. With the increase of piston dip angle, the average flow will increase, the flow pulsation amplitude and rate will decrease. What's more, the variations are both almost linear relationship.

Key words: axial piston pump with concial cylinder, air content in hydraulic oil, flow characters, AMESet, AMESim
