| Abstract: | A novel 2-D micro-positioner drived by PZT was introduced,which is based on the double flexible hinges in a structure of parallel four-linkage.The expression about the influence of dimension on the natural frequency of the worktable was deduced,and the parameters that effect the natural frequency greatly were found out by using FEA.The simulated results were compared with the corresponding experimental ones in order to analyze the factors influencing the dynamic properties,and it provides a theoretical and experimental basis for the design of micro-positioner. |
