The mechanism under consideration consists of two parallel cylinders, one inside the other, in close distance and relative motion. The unknowns of the problem are the equilibrium position of the inner cylinder and the pressure of the lubricant described by the compressible Reynolds equation. To complete the system, Newton's second law gives the equilibrium of forces. We present results on existence of solutions for a range of applied forces F.Rene Dager SalomonMihaela NegreanuJose Ignacio Tello del Castillo2017-03-31T15:28:29Z2017-03-31T15:28:29Zhttp://oa.upm.es/id/eprint/44843This item is in the repository with the URL: http://oa.upm.es/id/eprint/448432017-03-31T15:28:29ZAn inverse problema for the compressible Reynolds equationWe study the existence of solutions to a system of equations for equilibrium positions in lubricated journal bearings under load effects.

Lubrication is employed to reduce friction and avoid contactS. CiupercaM.

Three biological processes are taken into account: diffusion, degradation and reversible binding. We prove existence and uniqueness of solutions and its asymptotic behavior.Jose Ignacio Tello del Castillo
