Abstract

Based on Finite element method (FEM), analysis of natural frequency and dynamics response is carried out in this work. Firstly, modeling of rotor system in steam turbines is analyzed with Euler-Bernoulli beam element. Secondly, natural frequency of the rotor system is obtained and compared. Thirdly, dynamic response of the rotor system is simulated and the vibration of the rotor system is obtained. The results show that the proposed model can obtain results with high accuracy, and the model is efficient. The modeling approach presented in this work provides a fast and accurate method in analyzing dynamic characteristics of the practical rotor system in steam turbine units
