The inherent problems of rotating machine dysfunction are often caused by shaft misalignment. This defect generates some important loads and vibrations, and can lead to a premature failure of the bearing, the shaft, or the clutch. In this study we propose a model of a clutch having eleven degree of freedom and three types of nonlinearity introduced by dry friction, double-stages stiffness and splines clearances. The Coulomb friction formulations and splines clearance functions are smoothened before they are applied to the nonlinear system. The calculation of the dynamic response of the clutch is done by the Runge Kutta method. The dynamic behaviour of both a faultless clutch system and clutch system containing a parallel and angular misalignment defect are compared in the time domains. Finally, the effects of a harmonically varying load on the dynamic response of the defected clutch system with nonlinear dry friction and under sinusoidal torque excitation are analysed.
