摘要/Abstract

摘要： 针对油液含气影响油液流体属性,进而影响轴向斜柱塞泵流量特性的问题,在理论分析的基础上,利用AMESet自定义了流体属性、柱塞/斜盘作用通用子模型,仿真验证了流体属性通用子模型的适用性,并利用 AMESim建立整泵仿真模型。仿真研究了不同油液含气量和柱塞倾角对斜柱塞泵流量特性的影响,结果表明：随着油液含气量的增大,泵出口平均流量减小,容积效率减小,流量脉动幅值和脉动率增大;随着柱塞倾角的增大,泵出口平均流量增大,流量脉动幅值和脉动率减小;且各变化均大致呈线性关系。

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
