Abstract

The low-altitude rocket automatic docking and fueling situation requires posture adjustments under eccentric heavy loads, demanding spatial translation capabilities from the docking mechanism. During docking, the mechanism must withstand substantial forces applied at a point distant from the connection interface with the equipment. This paper proposes a novel of two degrees of freedom (DOF) translational parallel mechanism (PM) with completely separated drive and constraint branches. Its drive branches are unaffected by constraint force. The novel PM is suited for pose adjustment in heavy-load eccentric conditions, featuring excellent force performance and the ability to undergo specific optimization of branch layout based on predefined conditions. In order to make it applicable to the rocket automatic docking and fueling situation, the novel PM was combined with the single DOF moving guide to form the 3-DOF translation hybrid mechanism. Optimization strategy have been proposed. And dimension optimization was applied to it and traditional 3-DOF translation PM. The result revealed that, compared to traditional PM, the hybrid mechanism composed of the novel PM and the moving guide demonstrates superior optimization performance and is particularly well-suited for rocket automatic docking and fueling situation.
