Unbalanced Response and Design Optimization of Rotor by ANSYS and Design Of Experiments

In this paper harmonic analysis of rotor is done to identify the frequency through variation in the diameters by design of optimization (DOE) and ANSYS parametric design. In DOE two levels were used with total eleven diameters as parameters, which resulted in forty eight runs as per Plakett-Burman design to obtain responses using ANSYS. The effect graphs were studied to identify the diameters which are responsible for producing major effects on the frequency. It was seen that diameters D10 and D12 producing major effects, which were then used to identify the critical frequency of rotor.
