Abstract
To study the influence of structural static errors and spherical joint clearance on the kinematic accuracy of a 2(3PUS + S) parallel manipulator, error modeling and calibration are carried out. On the basis of error sources analysis, error model is established under the perturbation condition. The equivalent error vector of the spherical joint clearance is deduced through the orientation of the constraining force. With the consideration of the structural feature of the parallel manipulator with two moving platforms, error identification and calibration strategies are studied. Furthermore, under the constant trajectory, relationship between the posture accuracy and the structural parameters is analyzed.
