轴向柱塞泵滑靴的动力学特性仿真分析
|
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。
The matching between the slipper the swash plate,the piston,the retainer plate important to ensure the normal operation of the piston pump. First of all,the theoretical analysis of the force on the slipper of the A4VG125 type piston pump is carried out and we apply Simulation X to establish one-dimensional hydraulic model and threedimensional MBS model of the piston pump to simulate the pressure at the bottom of the piston. Then the hydraulic model is combined with the dynamic model established by ADAMS and ANSYS to complete the rigid-flexible coupling and fluid-solid coupling simulation model of the piston pump. The dynamic characteristics of the friction pair between the slipper and the swash plate,piston and retainer plate are analyzed by the simulation. The results show that,when the angle of the swash plate and the spindle speed are increased,the influences on the stress of the slipper and the working condition between slipper and piston pump are larger,and the force fluctuation of the spherical friction pair is more serious.
