ACTIVE 3D.O.F. STIFFNESS ELEMENT

A dynamic three-degree-of-freedom actuator/transducer element comprising at least three piezoceramic actuators and force sensors, as integrated stacks, which are preloaded in the housing by a low-stiffness tension bar, and are constrained, by means of a flexible shell, against shear force and torsion moment, whereby the element, when powered by external voltage source, is able to generate a dynamical axial force and displacement and dynamical bending and moment in the two principal tilt degrees of freedom around two orthogonal axes perpendicular to the principal displacement. When subjected to an axial force or a tilting moment, the transducer is able to generate charges that are proportional to the exerted force and moments.
