In this paper an analysis of the Elastohydrodynamic lubricated circular contact through a hybrid technique is presented. In particular the attention is focused on the pressure distribution calculation. A versatile code has been developed, able to evaluate the pressure distribution starting from 3-D film thickness maps obtained from the analysis of the interferometric images. The code is developed in C++ and is based on Multigrid Technique. This hybrid technique has a basic advantage with respect to the full numerical approach: the pressure is obtained without making any assumption about the lubricant itself. The main disadvantage of the method is that high resolution of the interferometric images is requested.

Abstract
In this paper an analysis of the Elastohydrodynamic lubricated circular contact through a hybrid technique is presented. In particular the attention is focused on the pressure distribution calculation. A versatile code has been developed, able to evaluate the pressure distribution starting from 3-D film thickness maps obtained from the analysis of the interferometric images. The code is developed in C++ and is based on Multigrid Technique. This hybrid technique has a basic advantage with respect to the full numerical approach: the pressure is obtained without making any assumption about the lubricant itself. The main disadvantage of the method is that high resolution of the interferometric images is requested.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
