AN OPTIMUM FIRST MODAL SHAPE FREQUENCY FOR FLEXIBLE DISPLACEMENT AMPLIFIER MECHANISMS

Abstract

This investigation analyzed the influence of design variables of a new flexible hinge displacement amplification mechanism such as variable L, y, t, x on the first modal shape frequency of this
mechanism. The Taguchi method is based on finite element analysis in ANSYS to optimize the first modal shape frequency of this mechanism. The FEA outcomes indicated that design variables have significantly affected the first modal shape frequency of this mechanism. And the problem was verified by analysis of variance, analysis of the signal to noise, and regression analysis of frequency. The optimal outcomes of frequency obtained 85.268 Hz. While the predicted outcomes of the frequency of the regression equation and the Taguchi method achieved 82.213 Hz and 82.459 Hz, these results are good agreement with error deviation percent of 3.47% and 3.29%, respectively.
