| Abstract: | Some research on the stress, deformation and modal of the root of an axle flowing type hydraulic turbine before and after thickening are made through ANSYS finite element emulation method. And the effect of stress buffer trough for reducing the stress is analyzed. The conclusion is that the condition of stress concentrating on the joint of hydraulic turbine blade flange and inner edge is improved notably. |
