Název v původním jazyce

Limitations of finite difference methods in the computation of coupling forces prescribed by the Reynolds equation

Popis výsledku v původním jazyce

This paper deals with the numerical modelling of journal bearings. They are mainly used for supporting rotating systems and powertrains. The bearing joint can be mathematically represented by a non-linear hydrodynamic force or linearized coefficients of stiffness and damping. The pressure distribution in a thin viscous oil film is described by the Reynolds equation, which can be solved in a basic form only by numerical methods. This paper aims at solving and applying the finite difference method (FDM). Moreover, problems and characteristic properties of the chosen method are described in detail.
