Finite element harmonic solution of The coupled rotor-bearing system

摘要

The dynamics of rotor vibrating periodically in an incompressible viscous fluid is considered in thernpaper. Based on Galerkin finite element method, the fully coupled rotor-fluid dynamic equation is established.rnInfluence of rotor unbalance, gap, eccentricity on fluid field and rotor vibration are calculated and analyzed. Somernuseful results are given in the end of paper.
