    Abstract

    This paper discusses the development of a numerical solver for the Reynolds equation in aerodynamic lubricated bearings, utilizing a finite difference method with multigrid. The advantages of the numerical method are that the number of operations and the memory capacity needed are almost proportional to the number of gridpoints involved. It is second order accurate and can cope with various bearing geometries. A survey is also given of the implemented modifications of the Reynolds equation. The efficiency of the method is demonstrated by two examples, namely: the dynamic tracking of the centre of a herringbone grooved journal bearing and the equilibrium position of a hard disk slider.
