Mercoledì 28 Maggio si terrà un seminario presso l’aula Grandori (Edificio 4) dalle ore 11:00 dal titolo “Nonlinear dynamics and vibration suppression of conceptual airfoil models under random loads“.

Il seminario sarà tenuto dal Prof. Yong Xu, Northwestern Polytechnical University, Xi’an (China).

Abstract

An aircraft in practice undergoes complex uncertain loads like turbulence, crosswind, pressure fluctuations, etc., that will have a substantial impact on its flight safety. It is of extreme significance to explore the complex nonlinear dynamics and vibration control for a conceptual airfoil model with random loads. The coupling interaction between structure nonlinearities and stochasticities can lead to some difficulties on the airfoil models, including the modelling, response solving, and vibration suppression. This talk will review our developments towards nonlinear dynamics and vibration suppression, especially for the stochastic dynamics, early warning, and data-driven problems, of the conceptual two-dimensional airfoil models. All the findings would be helpful in ensuring the flight safety and enhancing the strength and reliability of airfoil structure operating at complex flight conditions. Besides, several potential directions that are worth further exploring are also highlighted.
