Abstract
The “finite element method” of structural analysis and the “mobility method” of bearing analysis are combined for the computation of main bearing load and displacement cycles (together with such secondary performance variables as film thickness and shaft stress).
A numerical example for a production engine illustrates problem-dependent discrepancies between results of present and previous computation methods.
