Abstract
Provided is a method for analyzing oil film multi-field coupling characteristics of series friction pairs of an axial piston pump in the disclosure. According to the disclosure, based on an oil film independent analysis model of macro structures, motion states and heterogeneities of service conditions of three major friction pairs of the axial piston pair, surface microstructures of the friction pairs is introduced, and a solid-liquid-thermal multi-field coupling analysis method of the friction pairs is proposed for macro information interaction. Finally, a coupling solution of the oil film bearing characteristics of the multi-friction pairs of the system is realized by the multi-scale and multi-degree-of-freedom hydraulic-dynamic global coupling method.
