Paper No: IMECE2011-63509
... cover becomes very important. Because the cover material is visco-elastic, the delayed recovery response of the polymer during each roll revolution starts to initialize self-excited vibrations. This contact vibration is known as barring. A piezoelectric actuator is an excellent device for vibration...

... and each axis is comprised of a doubly-clamped beam and a parallelogram hybrid flexure with complaint beams and circular flexure hinges. The doubly-clamped beam that is actuated by a piezoelectric actuator acts as a linear prismatic axis. The parallelogram hybrid flexures are used to decouple the actuation...
