| Abstract: | It is significant for the design and application of a parallel kinematic machine to study the flexibility indices and its workspace distributions. In this paper, the relationships between the applied force and the deflection of a novel 6-DOF parallel kinematic machine based on the 6-SPS orthogonal three-dimensional platform mechanism are investigated.By using the submatrices of the flexibility matrix, the flexibility indices at any configuration of the parallel kinematic machine are proposed. The distributions of the indices in constant-orientation workspace are presented, which can provide the theoretical background for the optimal task planning and the analysis of machining error due to the deflection of the parallel kinematic machine. |
| Keywords: | DOF parallel kinematic machine orthogonal three-dimensional platform mechanism flexibility distribution |
