Abstract: We propose using viscoelastic damping with combined hardening and free-play structural nonlinearities to enhance energy harvesting performance and control vibration in a pitch and plunge airfoil with piezoelectric transduction. ...

Abstract: The demand for detecting minute mass in biology and chemistry promotes the research of high sensitivity and strong robustness mass sensor based on MEMS resonators in the past few decades. The nonlinear behaviors are ...

Abstract: Comparing to linear vibration absorbers, nonlinear energy sinks (NESs) have attracted worldwide attention for their intrinsic characteristics of targeted energy transfer or energy pumping in a relatively wide frequency ...
