Full TextAbstract
In this paper, the effect of shaft rotation on its natural frequency is investigated. Considering rotary inertia and gyroscopic momentum, the fourth order differential equation representing the flexural vibration of the shaft is solved in the new analytical method. The distributed lumped modeling technique (DLMT) is applied to obtain the transfer matrix for the distributed elements using the proposed method, and for the lumped elements consisting rotary inertia and gyroscopic effects. The results obtained by this method are compared and verified with the results of two other methods. The effects of shaft diameter, shaft length and disk inertia on the natural frequency are discussed for various speeds. It is shown that while the new method brings highly accurate results, its simplicity and accuracy provide proper application for the industrial systems.
