1. Vibration control device for steel tubular towers of Horizontal Axis Wind Turbines
Abstract This paper presents and discusses the design of a vibration control device for a 120 m high steel tubular tower of onshore Horizontal Axis Wind Turbine (HAWT). The tower is modeled using beam (own code), and shell and solid finite elements (via ANSYS). The Dynamic Vibration Absorber (DVA) is designed to be attached to the tower top, aiming to analyz

2. Synthesis of a Magneto-Rheological vehicle suspension system built on the variable structure control approach
The synthesis of a magneto-rheological vehicle suspension system built on the variable structure control approach is considered in the present work. The suspension is synthesized in order to improve the ride comfort obtained by a standard passive suspension. Although a nominal half-vehicle model with rigid body is considered in the synthesis of the suspensio

3. Projeto, construÃÃo e caracterizaÃÃo de um amortecedor ativo controlado por atuador piezoelÃtrico / Design, construction and characterization controlled by Piezoelectric Actuato
This thesis presents the design methodology, the construction of a prototype and the experimental validation of an active vibration damper witch is controlled by a piezoelectric actuator. The proposed device has two flexible metallic bellows connected to a rigid reservoir filled with a viscous fluid. When one of the bellows is connected to a vibrating struct
