| Summary: | As a typical bionic foot walking robot, hydraulic quadruped robot has attracted much attention due to its high mobility, strong load capacity and smooth motion The electrohydraulic servo cylinder, as its power actuating element, requires low friction, good resistance to lateral load and high speed motion The research object of this paper is the hydrostatic sealing hydraulic cylinder guide sleeve The oil film characteristics of the rectangular oil cavity and the Ishaped oil cavity of the hydrostatic bearing guide sleeve are analyzed and compared with the FLUENT software The relationship between piston rod movement speed and eccentricity and oil film bearing capacity, friction and leakage is analyzed The relationship between inlet flow rate and oil film bearing capacity, friction force and inlet pressure and leakage volume is analyzed It provides a theoretical basis for optimizing the static pressure bearing seal parameters |
