Nonlinear dynamics is widely exploited in micro-mechanical resonators with a number of applications. One of the crucial issues in these applications is to intentionally tailor the intrinsic nonlinearity in these structures. In this study, a structural optimization methodology is improved for tailoring the intrinsic nonlinearity in these resonators by manipulating their structural geometry.
In the optimization, the objective function is defined based on the nonlinear modal coupling coefficients as well as eigenfrequencies and modal shapes of the vibration modes. A preliminary study shows that the improved formulation of the optimization problem enables better designs.
