Abstract:

The transverse wind effect could lead to the dramatic vibration of the slender engineering structures, such as the wing of aircrafts during their taking off and landing process. In this paper, the transverse wind effect on a slender beam structure with variable cross-section is studied by an accurate numerical model solving the vibration response of the slender beam. Furthermore, a piezoelectric patch connected with a feed-back control circuit is employed to realize the active vibration control of the beam structure subjected to a strong wind excitation. From numerical simulations, an optimal design of the feed-back control gain factor, the size and location of the piezoelectric patch is given to reduce the vibration amplitude of the slender beam structure at the most.
