Abstract
Calculations for temperature and thermal deformation in finite tribological systems usually require finite-element (FEM) procedures. Because these calculations may be intermediate steps in iterations for film thicknesses and pressure distributions, combining FEM procedures into the iteration process may be considerably costly or even impractical. This paper reports the development of two influence functions for calculating the steady-stale temperature and the consequent thermal deformation for finite mechanical structures, as well as a method that utilizes these influence functions for thermal analyses of complicated tribological systems. A sample calculation on the thermalelasto hydrodynamic lubrication (TEHD) of a journal bearing was conducted; the results showed that this method is convenient to use and can considerably save programming effort and computation time.
