HYBRID VIBRATION ISOLATION WITH THUNDER ACTUATORS

摘要

The THUNDER piezoelectric actuator is a newly developed active control device that possesses many advantages compared to other classical piezoelectric actuators. Particularly, its capacity in generating high displacement and its inherent fallibility make itself an ideal candidate in active isolation application. This paper concerns the simulation, design and experimental tests of an isolation prototype using THUNDER actuators. Different aspects concerning its use in practical situations are first investigated. Its dynamic properties are then modeled using a mechatronic approach. A dynamic model is established considering the parameter evolution due to the mass loading. A simple prototype is finally designed using three THUNDER actuators. Both simulation and experimental tests show the potential of THUNDER actuators in active vibration control applications.
