This thesis is focused on the comparison between Numerical Calculation and FEM Analysis by ANSYS by software for Impeller Shafting System of Low Noise Large Cavitation Tunnel. The impeller shafting system are considered buoyancy effect to influence driving shaft in the water that reason why the shaft diameter 800㎜ above. The shafting are arranged two solid shafts at forward end, three hallow shafts in the water and one hallow shaft on the tail. The bearings are arranged one self aligned journal bearing on the tail shaft and one axial thrust with two journal bearings on the motor shaft. The strength calculation was done by MathCAD.
