| Abstract: | Based on parallel mechanism kinematics and probability theory,the joint error analysis of a 3-DOF parallel machine with actuation redundancy(PMAR)was presented.The effect of sphere joint clearance on the position error of the platform center was carried out and then error distribution function was derived.The result provides a theoretical foundation for the error analysis of PMAR,and the method of improving accuracy of PKM by actuation redundancy was got through this research. |
