  Nonlinear Dynamics of MEMS Resonator with Squeeze-film Damping

  By Ashish Kumar Gur jar, J. Srinivas

  Abstract: This paper presents nonlinear dynamic analysis of electro-statically actuated micro-resonator under squeeze-film damping conditions. By considering a single degree-of-freedom oscillator model of resonator with squeeze-film damping effects, nonlinear phenomena are investigated. Numerical studies are conducted using phase portrait and Poincare map over a range of AC voltage amplitudes to predict the dynamic pull-in state. The effects of AC harmonic frequency and ambient pressure on beam dynamics have also been studied. …

  Design and Analysis of Nano-Vibratory Beam Gyroscope

  By Ashish Kumar Gur jar, J. Srinivas

  Abstract: This paper presents the modeling and analytical simulation task of a nano cantilever beam gyroscope. Micro/nano gyroscope as an effective rate measurement sensor is of extreme importance in several modern equipments including aircrafts, satellites and even in small cameras. Several types of such gyroscopes are in use and various research simulations were performed over the last one decade. Compared to tuning fork and ring type, the beam type gyroscopes are …
