| Abstract: | With reference to a symmetrical unbalanced rotor treated as a continuous elastic shaft suPPorted at its end by lubricated journal bearings,the short bearing model is adoPted. The nonlinear motion equations of the systems are derived and the journal orbits are determined as aPProximate solution of those equations. Numerical results are Presented in given oPerating conditions. |
