| Abstract: | An optimum adjustment is investigated of the shafting dynamic location of a large-sized turbogenerator unit. By the use of a finite element method and by taking account of the non-linearity of bearing oil film force established are the shafting nonlinear equation group of the said turbogenerator. With the help of an unconstrained minimization method solved is the axle center actual location of the rotor within its working speed range. |
