Abstract
A lumped parameters model of a rectangular air pad is developed for dynamic analysis. The model is valid for different geometries of the pad, which is supplied through multiples orifices positioned on a supply rectangle. The dynamic stiffness is analytically obtained by linearizing the system around the steady equilibrium condition. In this paper the model is validated with a distributed parameters model in static conditions.
