Design of single-DOF micro-displacement flexure hinge mechanism actuated by PZT
The displacement accuracy coefficient and the bending angle coefficient of flexure hinge are put forward in the paper. Then, a fast and easy parametric finite element analytic method based on APDL language in ANSYS is employed to study the relationship between the basic construction parameters of flexure hinge and the two coefficients. The analytic results demonstrate that the minimum thickness and the cutting radius of flexure hinge have strong influence on the displacement accuracy coefficient and the bending angle coefficient, while the results show the variation of the width of flexure hinge has little influence on the displacement accuracy coefficient and the bending angle coefficient. Finally, a single-DOF micro displacement with flexure hinge mechanism actuated by PZT is designed and the maximum displacement of the micro-displacement mechanism is 30 m μ .
