DOI: 10.1016/j.mechmachtheory.2019.103660

Abstract: Abstract In the transportation domain such as automotive turbochargers and aircraft turbines, the vibrations of on-board rotors are induced not only by the mass unbalance excitation but also by various movements of their support. The… read more here.

Published in 2020 at "Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science"

DOI: 10.1177/0954406220975431

Abstract: In this study, an analytical approach is presented to analyze the bifurcations and nonlinear dynamics of a cantilevered piezoelectric nanocomposite trapezoidal actuator subjected to two-frequency parametric excitations in the presence of subsonic airflow. The assumption… read more here.
