|Title:||Plate actuator vibration modes for levitation|
|Citation:||International Tribology Conference, Tokyo, Japan, 16-20 September 2015|
|Abstract:||The design of an aluminium or steel plate of various thicknesses for achieving levitation of a small aluminum disk is investigated by simulation using ANSYS. Each plate design is excited by an arrangement of four hard piezoelectric actuators driven with an AC voltage, which produces a centre displacement for generating a squeeze-film in the gap between the vibrating plate and the disk. Physical experiments show levitation conditions for one of the designs.|
