基于AMESim的斜盘式轴向柱塞泵脉动特性分析

摘要

Based on analyzing the working principle of swashplate axial piston pump, the pulsation coefficients of the pump's flow and pressure were calculated with classical formulas. Based on AMESim, a theoretical model of the pump was established, the pulsation coefficients were calculated through simulation and they were compared with theorical ones. Then a more realistic model was established and the pulsation coefficients of the pump's flow and pressure were calculated under different conditions. The research results provide a beneficial reference for the application of swashplate axial piston pump.%在分析斜盘式轴向柱塞泵工作原理的基础上,利用经典理论公式计算其脉动系数；利用仿真软件AMESim建立柱塞泵系统理论模型,通过仿真计算出脉动系数并与理论公式计算结果进行对比,验算AMESim仿真计算方法的正确性；考虑配流等实际条件建立柱塞泵系统的实际模型,通过仿真运算得出具有不同柱塞数的柱塞泵在不同工况下的流量脉动系数和压力脉动系数,为泵的应用提供有益的参考.
