【摘要】：滑靴与斜盘、柱塞、回程盘之间的配合是保证柱塞泵正常工作的重要条件,滑靴的磨损失效会影响与之配合零件的正常工作。首先对A4VG125型柱塞泵滑靴进行理论受力分析,应用Simulation X建立柱塞泵的一维液压模型和三维MBS模型,仿真柱塞底部所受液压力。然后与ADAMS和ANSYS建立的柱塞泵动力学模型进行联合,完成柱塞泵的刚柔与液固耦合仿真模型。在仿真工作参数作用下,研究滑靴与斜盘、柱塞、回程盘之间摩擦副的动力学特性。结果表明:当斜盘倾角增大、主轴转速提高时,对滑靴总体的受力/力矩情况影响较大;滑靴与柱塞之间的球铰副受工作参数变化影响较为明显,受力/力矩波动较为严重。
[Abstract]:The cooperation between slipper and tilted disk, plunger, return disc is an important condition to ensure the normal operation of piston pump. The wear failure of the slipper will affect the normal working of the matching parts. Firstly, the theoretical analysis of the sliding boots of the A4VG125 piston pump is carried out. One dimensional hydraulic model and three dimensional MBS model of piston pump are established by using Simulation X. The hydraulic pressure at the bottom of the plunger is simulated and then combined with the dynamic model of the plunger pump established by ADAMS and ANSYS. Under the action of simulation parameters, the dynamic characteristics of friction pairs between sliding boots and sloping disk, plunger and return disk are studied. The results show that: when the inclined angle of the inclined disk increases, the dynamic characteristics of the friction pair between the sliding shoe and the slider, the plunger and the return disc are studied. When the spindle speed is increased, the overall force / torque of the slipper is greatly affected. The ball hinge pair between the slipper and the plunger is obviously affected by the change of working parameters, and the force / torque fluctuation is more serious.

【正文快照】： 引言在轴向柱塞泵中,主轴带动缸体旋转时,斜盘通过滑靴与回程盘、滑靴与柱塞的配合,将柱塞从缸体中拉出或推回,完成柱塞泵的吸油、排油过程。其中,滑靴同时与柱塞、斜盘、回程盘接触,受力情况复杂,滑靴的磨损经常发生。滑靴磨损失效会影响柱塞泵的正常工作,严重时会导致泵的损
