Abstract

© 2020, International Information and Engineering Technology Association.Turbine rotors have complex geometry that is difficult to determine their dynamical behaviour. Strong approaches like finite element methods is used to analyze the small steam turbine system to eliminate difficulty of complex geometry problems. Finite element method saves time by allowing reductions in equations beside it is possible to obtain faster solutions by using software that can solve these equations. In this paper, rotor-dynamic analysis of a small steam turbine rotor with certain geometrical and mechanical properties was performed and critical speeds, modal shapes and Campbell diagram of the system was obtained by using FEM based Dynrot software.
