There are a lot of industrial machines that have moving plate or sheet. For example, they are a steel rolling mill, a tension leveler, a paper mill, a printing mill, etc. In these machines, a lot of vibration problem, which is caused by moving plate or sheet, happen. Especially, in a paper mill and printing mill which deal with thin sheet, it is thought that the flow of the surrounding air affect the vibration of the sheet. In this paper, we investigated fluid flow and damping of thin fluid layer between an oscillating plate and a rigid plate. The steady flow and the second and higher super-harmonic flow occur because of the nonlinearity of Navier-Stokes' equation. These components work as nonlinear damping.
