Abstract

The invention discloses an intelligent optimized design method of an axial piston pump, in particular to an optimized design method of an axial piston pump valve plate based on a particle swarm optimization method. The minimum peak value of the pressure gradient serves as the objective function under the condition of no pressure difference transition, and the optimized design is conducted on the structural parameter of the valve plate. According to the optimized design method of the axial piston pump valve plate based on the particle swarm optimization method, the symmetric deflection type valve plate, whereina damping groove is opened to serve as the basis, and the axial piston pump is built. After oil is sucked by each piston cylinder bore, the axial piston pump enters a pre-boost area to boost the characteristic differential equation in advance. After the oil is discharged by each piston cylinder bore, the axial piston pump enters a pre-pressure-relief area to relieve the pressure of the characteristic differential equation in advance. An updating mechanism which is searched by multiparticles in parallel applies the acceleration adaptive particle swarm optimization algorithm, and the optimal matching of the structural parameter of the valve plate is obtained. The optimized design method of the axial piston pump valve plate based on the particle swarm optimization method provides a high-efficient solution for how to reduce the pressure shock in the pump and how to suppress the noise.

Description

technical field [0001] The invention belongs to the field of intelligent optimization design of axial plunger pumps, and in particular relates to an optimization design method of a distribution plate of axial plunger pumps based on a particle swarm optimization method. Background technique [0002] Hydraulic axial piston pump is the most important hydraulic basic part in mechanical equipment, widely used in modern industrial mechanical systems, but axial piston pump is the most important source of vibration and noise in hydraulic transmission, and its structure noise and Fluid noise is mainly generated during the flow distribution process. The plunger hydraulic cylinder of the axial piston pump is constantly switching between high and low pressure during operation. When the plunger hydraulic cylinder filled with low-pressure oil is suddenly connected to the high-pressure oil chamber, the high-pressure oil will Instantaneous backflow to the cylinder, resulting in hydraulic sh...
