Theoretical and Numerical Study on the Dynamic Behaviour of a Rotor with a Conical Steel Shaft

This work proposes a theoretical and numerical study on the behaviour of the tapered rotor. The characteristics of the elements of the rotor are determined; it is to evaluate the expressions of the kinetic and potential energies as well as the virtual work corresponding to the basic elements disk, shaft, bearing for the two conical models by applying the method of the finite elements. Numerical simulation allows us to observe and determine modal analysis and natural values.
