摘　　要：本文研究了大型汽轮发电机组轴系动态位置的最优调整。用有限元法及考虑各轴承油膜力非线性,建立了大型汽轮发电机组轴系非线性方程组。用无约束极小化方法求解了转子在工作转速范围内轴心实际位置。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.
