In order to improve the precision positioning accuracy of image stabilization mechanism, a two-dimensional image stabilization mechanism with parallel decoupling was proposed. Firstly, according to the principle of lever-half-bridge hybrid amplification mechanism, the structure of two-dimensional image stabilization mechanism was designed, the working principle was analyzed, and natural frequency of the mechanism was calculated. Secondly, static analysis, modal analysis, and flexure hinge parameter optimization of the mechanism based on ANSYS were carried out. The simulation results show that two-dimensional image stabilization mechanism can realize the micro-displacement positioning function in the X and Y directions. The resonance phenomenon does not occur when the mechanism works. The thickness and width are the sensitive parameters of flexure hinge. Finally, the actuation performance of two-dimensional image stabilization mechanism was tested during the prototype, the relationship between the output displacement in the X and Y directions and the input voltage, frequency was tested, and the displacement coupling in the X and Y directions was tested. The experimental results show that the motion displacement of the mechanism is 103.9 × 104.8 μm, and the output displacement coupling does not exceed 7.5% of the stroke. The image stabilization mechanism can realize large stroke and precision positioning functions, and is feasible in engineering applications.
