Rotors Frequency and Time Response of Torsional Vibration Using Hybrid Modeling

In this paper, the application of distributed-lumped (hybrid) modeling technique (DLMT) in modeling of the forced torsional vibration of systems is investigated. To illustrate the simplicity and efficiency of the method, an industrial example of rotating shaft with a lumped element subjected to various torques is analyzed. Natural frequencies obtained by this method are compared with those obtained by using finite element and Holzer's method. In addition, time responses of the system subjected to three different types of torsional forces are computed by this method.
