摘要
针对轴向柱塞泵压力脉动特性问题,介绍了轴向柱塞泵工作原理,对其进行了运动学分析,推导了柱塞泵实际输出流量计算公式,得出了可能对其输出流量产生影响的因素。通过AMESim软件对不同转速、斜盘倾角、容腔体积、系统流量、内泄漏流量下柱塞泵压力脉动进行了仿真,分析各参数对出口压力、压力脉动幅值及频率的影响,并将仿真结果与某型液压泵压力脉动试验数据进行对比,得出仿真结果与试验数据压力脉动特性相似,为建模的正确性提供了支持。研究对于轴向柱塞泵工作参数的选择及柱塞泵压力脉动仿真及试验具有一定参考意义。
In view of the pressure pulsation characteristics of the axial piston pump,this paper introduces the working principle of the axial piston pump,carries out kinematics analysis,deduces the calculation formula of the actual output flow of the piston pump,and obtains the factors that may affect the output flow of the piston pump.AMESim is used to simulate the pressure pulsation of the piston pump under different speed,swash plate angle,cavity volume,user flow and internal leakage flow,and analyze the influence of each parameter on the outlet pressure,pressure pulsation amplitude and frequency.The simulation results are compared with the pressure pulsation test data of a certain hydraulic pump,and the simulation results are similar with the test data in pressure pulsation characteristics,which provides support for the correctness of the modeling in this paper.This paper has certain reference significance for the selection of working parameters of axial piston pump and the simulation/test of pressure pulsation of piston pump.
