Consideration on bent magnetic levitation apparatus for thin steel plate

Nihon Kikai Gakkai ronbunshu, 2015
In the transport system of a thin steel plate production line, there is a problem that the quality of the plate surface deteriorates over time because the plate is usually in contact with rollers.

A study on levitation performance improvement of bent flexible steel plate

Mechanical Engineering Journal, 2018
Levitation improvement of the bending levitation performance of thin steel plate was performed. First, the point of the steel plate where the vibration is predominantly generated was estimated using an ultrathin steel plate with a thickness of 0.18 mm ...

Transient amplitude behavior analysis of nonlinear power ultrasonic transducers with application to ultrasonic squeeze film levitation [PDF]

, 2012
In this article, force and self-excitation driving methods for ultrasonic transducers are compared with each other in sense of their transient amplitude behavior in the presence of nonlinearities. An equivalent circuit transducer model is simplified to a

Linear Parameter-Varying and Fixed-Parameter H_∞-Based Control of a Bearingless Compressor

IEEE Access
Bearingless machines have the potential to provide shorter rotors and achieve overall lower losses and higher energy densities than traditional technologies. However, levitation control has to overcome some further challenges.
