Nonlinear Mechanics of Suspension Beams for a Micromachined Gyroscope

Davis W.O., Pisano A.P., University of California-Berkeley, US

We present a method for the calculation of the coefficients of cubic stiffening for tether-suspended micromachined systems. The analysis is based on a nonlinear rod theory, and enables the prediction of the maximum achievable motion [...]

On the Vibrations of a MEMS Gyroscope

Davis W.O., Pisano A.P., UC-Berkeley, US

In this paper, the dynamics of a dual-axis MEMS gyroscope are examined. The model for the device is based on a non-linear rod theory developed by A. E. Green, P. M. Naghdi and several co-workers. [...]
