title = "Numerical analysis of the nonlinear restoring force based on near-field acoustic levitation",
abstract = "The stability of the floating object is a key factor in near-field acoustic levitation, which has an extensive application prospect in manufacturing of micro-electromechanical system parts. This study presents a numerical study of the restoring force based on the theory of gas film lubrication. Finite difference scheme is used to solve the Reynolds equation considering the movement of reflector and to obtain the air pressure distribution. After coordinate transformation, the restoring force which acts on the levitator can be acquired. An experimental rig is constructed to measure the restoring force with different eccentricity. The experimental results show that the restoring force increases with the increase of eccentricity. The numerical results match well with experimental results.",
