| Abstract: | The kinematic characteristics of 3PSS parallel mechanism was thoroughly analyzed. It was proved in theory that the motion of the movable platform is translation, and this kinematic characteristics of the mechanism was validated by the virtue prototype technology using the software of the dynamic analysis of mechanism systems ADAMS. The workspace of the movable platform of the mechanism was analyzed and the mathematic express of the workspace was given on the base of the theoretical analysis. The 3D configuration of the workspace was drawn up. This will establish the foundation for the locus plan of the mechanism. |
