Résumé: | n recent years, machine component design has been a major con-
cern for researchers. Emphasis has been placed especially on the analysis of
bearing systems in order to avoid detrimental contact. The shaft misalignment
is one of the most problems that affects directly the operating conditions of
these components. In this context, the present study proposes a reduced-order
method "Proper Generalized Decomposition" (PGD) using the separation tech-
nique through the alternating direction strategy to solve the modified Reynolds
equation, taking into account the presence of misalignment in the shafting sys-
tem. The solution shows the representation of two types of misalignment ge-
ometry, especially axial and twisting. A comparison of the results between the
proposed approach and the classical method, through several benchmark ex-
amples, made it possible to highlight that the new scheme is more efficient,
converges quickly and provides accurate solutions, with a very low CPU time
expenditure. |
