| Abstract: | Through varying the joints' distribution, 10 typical 3-SPR parallel manipulators were derived and their displacement char-acter was analyzed. CAD dimension driving technique was used to solve the workspace, and parameters to describe the workspace and orientation of the moving platform were defined. Workspaces and orientation scales of the 10 manipulators were compared, the influence of the joints' distribution to which was analyzed. |
