The dynamic analysis model of axial piston pump was established; both the kinematics and dynamics simulation analysis were conducted by virtual prototyping approach. The displacement, velocity, acceleration and stress curves of the piston under different working conditions were investigated. In addition, a ball-in-socket contact model was established, and the effects of hydraulic pressure, piston radius and radial clearance on normal displacement, contact radius, maximum contact pressure, normal contact stiffness and tangential contact stiffness were analyzed comprehensively. The results indicate that the normal displacement, maximum contact pressure, contact radius, normal contact stiffness and tangential contact stiffness can be improved by enlarging the piston radius and decreasing the radial clearance.

In order to improve the friction performance of the valve plate and improve the oil film bearing capacity of the valve plate, the influence of the fluid-solid coupling on the performance of the oil film of the valve plate was studied. The lubrication characteristics of the surface texture of the valve plate were studied systematically based on the theory, simulation and coupling effects. In this paper, the geometrical model of hydraulic drive valve plate is established, and the thickness and pressure equation of hydraulic film are deduced theoretically. The Reynolds equation is solved by the finite difference methods. The film thickness and pressure distribution under fluid-solid coupling of the port plate pair are obtained, and the correctness of the theory and programming is analyzed.

“…They found from the experiment results that the inlet pressure increase will lead to an increase in oil film thickness and thickness variation range. 13 Zloto 14 proposed that the unbalance of the pressing torque and oil film support torque results in the tilt of the cylinder block. The experiments of Richardson et al 15 showed that the minimum oil film thickness appeared on the oil suction side.…”

Due to the unbalanced effect of force and torque on the axial piston pump cylinder block, a wedge angle of oil film exists between the valve plate and the cylinder block. The cylinder block tilt seriously affects the oil film and the distributing pair lubrication state, leading to boundary lubrication appears in some cases. To reduce the impact of the tilt on the cylinder block of axial piston pump, the magnetic auxiliary support (MAS) for the pair is proposed. The MAS reduces the overturning torque on the cylinder block by the auxiliary magnetic support. Then the tilt characteristics of the cylinder block are improved. In this paper, the cylinder block overturning torque equations under the support of MAS are established, and the improvement of overturning torque is analyzed. An experimental platform was constructed to measure the thickness of the oil film of the pair and test the tilt of the cylinder block. The experimental results showed that the MAS can effectively improve the tilt of the cylinder block and the performance of the axial piston pump. This method has certain reference significance for the research of axial piston pumps.
