Název v původním jazyce

A system for the vibration suppression in the broad frequency range using a single piezoelectric actuator shunted by a negative capacitor

Popis výsledku v původním jazyce

A system for the vibration suppression using a single piezoelectric actuator is presented. The method is based on the fact that the transmission of vibrations between two objects can be reduced through an extremely soft element, which is placed between those objects. It is also known that by connecting a negative capacitor to the piezoelectric actuator it is possible to create an element whose elasticity can be arbitrarily tuned. Therefore, by combining these two principles, a new vibration control system, which consists of a piezoelectric actuator connected to a negative capacitor, has been realized. It is shown that such an arrangement allows the realization of a simple and compact system, which, however, offers great vibration isolation efficiency in variable vibration conditions.
