| Abstract: | In the bulb turbine, main shaft and stay column play important role. Main shaft is positioned horizontally. More stress concentration occurs near the junction of stay column with concrete at the top and bottom, since the entire load is being taken care of by stay columns at the top and bottom. A finite element analysis (FEA) has been made using ANSYS software to find out structural stability with stress distribution for bulb turbine and the reasons for high vibration and vertical cracks in the concrete structure of the powerhouse. Results from FEA analysis show that the bulb turbine operation is safe when the stay columns are fitted with pipe jacks. This method reduces stress concentration at the junction of stay column with concrete. |
