Moreover, serious stick–slip vibrations of the drill string is the main factor leading...

...Mohammad A. Al-Shudeifat; Ayesha Al Mehairi; Adnan S. Saeed; Shadi Balawi The application of the proper orthogonal decomposition (POD) method to the vibration response of a cracked rotor system is investigated. The covariance matrices of the horizontal and vertical whirl amplitudes are formulated...

...-periodic motion were observed in the range of study. The influence of various parameters on the response of the system is studied. A main contribution is that the parametric excitation in the presence of nonlinearity can be used to suppress the forward synchronous vibration. Indeed, in the presence...
