A reduced-order method with PGD for the analysis of misaligned journal bearing

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