Effects of textured journal bearings on vibrations of lightweight rotors

Abstract : A dynamic model of a rotating shaft on two textured hydrodynamic bearings is presented. The hydrodynamic mean pressure is computed using multi-scale periodic homogenization and is projected on a flexible shaft with internal damping. The steady state solutions of an unbalance response are analysed with two sinusoidal texturing patterns. The stability zone and the amplitude of limit cycle are presented. The harmonic balance method applied to the monolithic resolution of the fluid structure coupling is efficient and allows parametric studies of stability.
