Design of the Hydraulic System for Carrying Manipulator with 6-DOF

According to the requirements for wheel hub assembly line, the structure and hydraulic system of carrying manipulator with six degrees of freedom (DOF) is designed. The working principle of the hydraulic system is analyzed. To minimize the output force of the hydraulic cylinder, a mathematical model of hydraulic cylinder output force and structural parameters is established. And then the manipulator structure is optimized based on Matlab software. The key components of the hydraulic system are selected. This research provides reference for design of similar hydraulic system of industrial robot.
