| Abstract: | In order to design a parallel robot with good kinematic performance,this paper takes 3-UPU parallel robot driven by non-friction pneumatic cylinder as the research object,and carries out kinematics modeling,workspace and dynamics simulation analysis.The physical model of 3-UPU parallel robot is designed by three-dimensional modeling software;the kinematics equation is deduced according to the geometric relationship of the robot and the workspace of the robot is obtained based on numerical method;the range of rotation angles of each branched chain of the robot is solved by ergodic method,thus obtaining the maximum output force distribution of the robot in its workspace.The simulation results show that the robot has good kinematics performance. |
