Fem model for calculation of hydro turbine shaft
Апстракт
This paper describes the real problem calculation of stress state of hydro turbine shaft with crack appearance on shaft-flange radii. Finite element method (FEM) is used for calculation of shaft stress state and shaft deformation and the 3D FEM model development is described. The paper gives detail description of used finite element type and for the simulation of external loads on FEM model. FEM calculations are per formed for the case of normal service regime. In the analysis, the load carrying capacity of critical radii is calculated. Also, the numerical results for stress state of shaft-flange finite element model are used for stress concentration factor calculation. The obtained results for stress state and stress. concentration factor follow to conclusions about load currying capacity of shaft-flange radii.
