    Optimization effects of design parameter on the first frequency modal of a Bridge-type compliant mechanism flexure hinge by using the Taguchi method

    ABSTRACT:

    The compliant mechanism always requests high displacement amplification ratio and high vibration frequency. Therefore, this paper optimized design parameters to obtain the maximum value of the first frequency modal shape using the Taguchi method. First, the model was designed by Solidworks. Second, effect design parameters on the first frequency modal shape were analyzed via ANSYS Workbench 18.0, and the final the maximum value of the first frequency modal was obtained by the Taguchi method. The simulation results revealed that the thickness and width of flexure hinge has a significant effect on the first frequency modal. The S/N analysis results demonstrated that the thickness of the flexure hinge has a significant affect next to the width of the flexure hinge, inline angle between two flexure hinges, input body length, and the fillet radius of the flexure hinge. The ANOVA analysis results identified that the contribution percentage of design parameters and fillet radius of the flexure hinge have a significant effect on the first frequency modal. The R-square was obtained at 99.84%, and the maximum value of the first frequency modal was obtained at 821.8267 Hz.
