A new non-contact liquid bearing, which utilizing traveling waves, is developed in this paper. The developed bearing is designed in an octagon shape where series of piezoelectric actuators are placed between a rigid support plate and the elastic thin bearing surface around the circumference and in the radial direction. The driving apparatus for the developed bearing is implemented based on DSP and voltage amplifiers. The liquid film force induced by traveling waves is confirmed by experiments which prove the feasibility of the developed bearing.

Finite Hankel Transform

The solution of the momentum equation describing unsteady creeping flow of the liquid film during its initial period of drainage on a cylindrical surface has been obtained by the method of finite Hankel transform. The steady-state solution describing the later stages of the drainage process [1, 2] has been deduced by letting the time since the start of motion to be infinite. For completeness, the derivation of the velocity distribution for the vertical plane case applying finite sine transform (equivalent of finite Hankel transform for a cylindrical surface) has also been included.
