Název v původním jazyce

Vibration suppression and shape change of thin plate by clusters of actuators

Popis výsledku v původním jazyce

Smart materials are increasingly being used in today´s everyday life. Yet basically each machine is surrounded by a simple protective covering material. This cover is intended to protect machine, operator, reduce noise, vibration and so on. One of the vibration cases studied is flutter. Flutter phenomena are seen when vibrations occurring in an aircraft match the natural frequency of the structure. If they aren’t properly damped, the oscillations can increase in amplitude, leading to structural damage or even failure. Work focuses on the research of creating such a smart material that is able to suppress vibration or even change its shape. Studied way is that the base material is equipped with a uniform network of piezo sensors and actuators, which are divided into individual units (clusters). It is then possible to design a single cluster control and apply it to a large structure, such as the wing of aircraft.
