CALCULATION OF THE HYDRODYNAMIC LOAD CARRYING CAPACITY OF POROUS JOURNAL BEARINGS

Abstract

This paper is about the calculation of hydrodynamic load carrying capacity of porous journal bearings. Pressure functions were determined and compared to each other to show the differences of several simplifications, assumptions and boundary conditions. The porous material was assumed to be isotropic and homogeneous. Four pressure functions were analysed using the short bearing approximation and one pressure distribution with the infinitely long bearing assumption. The load carrying capacity and the coefficient of friction were calculated and compared to one another.
