Influences of forced frequency and its Static Analysis of Kaplan Turbine Shaft with Different Engineering Materials

In the present investigation, the SolidWorks software tool was employed for failure analysis of the Kaplan turbine shaft using modal test analysis. The failure analysis has been performed the concerning applied load at different frequencies (285.92, 288.69, 348.65, 353.12, 369.23, and 382.65Hz). The turbine shaft generally fails due to excess load and high speed, such type of failure can be minimized using optimal load and appropriate materials. Shafts are the generally used in the turbine and it is subjected to failure due to a large number of stresses induced at the coupling of shaft and flange. This analysis was carried out for different materials used and analyzed which material was more suitable for this application on behalf of the yielding strength of the materials. The main objective of this work is appropriate material for the shaft and reduced the value of stresses. In this work, two types of material (AISI-1040 carbon steel and Forged steel) have been taken and performed the test to get the desired property.
