DESIGN AND ANALYSIS OF STEAM TURBINE ROTOR

Rotor is an very important part in the machines,especially in the rotating machines like gas and steam turbines. In this paper steam turbine rotor is analysed by using finite elements. In the complex systems, many of the engineering problems, it is difficult to solve the problem by closed form or exact solution method. Then we have to go for some numerical/approximate method for solving the problem. There are lot of numerical/approximate methods available. Finite element technique is an numerical method used for many engineering applications very widely. We have analyzed the rotors acted by different mechanical & thermo-mechanical loads, and analysed to find out the behaviour of the rotors. In the analysis results it is seen that the solid rotor is better than the hollow rotor.
