Dynamic performance indices of a spatial rotation 4-SPS-1-S parallel manipulator has been studied. The 4-SPS-1-S parallel manipulator has spatial three pure rotation degrees of freedom, including four SPS active legs and one passive constraining leg. Based on the velocity mapping equations of the mechanism, Jacobian matrices were built and computed. The dynamic performance indices which include load capacity performance and actuating performance were introduced and defined, and analysis equation for assessing the load capacity and actuating performance of the parallel manipulator mechanism was built. Finally a numerical example was provided for analyzing the dynamic performance indices distribution rules over the entire workspace.
