Abstract
Centrifugal pump is world one of the oldest water pumping devises. The current work deals study Shaft of centrifugal pump for static and dynamic analysis. As we know rotodynamic machineries are designed keenly as there is lot of fluctuation in the loads and speeds. The shaft is analyzed by using finite element analysis technique for stresses and deflections. The total work is carried out in two stages first stage is static analysis. In this stage pump shaft is analyzed for stresses and deflection and same results are verified using graphical integration method. And second for dynamic analysis, in this stage result obtained by static analysis are used to calculate dynamic forces coming in pump shaft. Again shaft is analyzed in dynamic input condition and results are verified by using graphical integration method. The software used for the finite element meshing is HYPERMESH and solver used is RADIOSS. Result values obtained for deflection and stresses are compared in both cases. Result obtained by graphical method and FEA are nearly similar and are in acceptable limits.
