Abstract: In this paper, a whole analysis of the large bulb type turbine generator is introduced by FEM (finite element method)
The strength and stiffness of FEA results are discussed at all cases, and the modal frequency of the whole unit is obtained by modal analysis, which provides a foundation and direction to avoid renounce efficiently
