This paper proposes torsional vibrations of the clearance problem in coupling, joint and clutch for a rotating shaft system. To make researches into the vibrational phenomena of the system, bilinear spring stiffness models with hysteretic torque in clearance are developed. The dynamic behavior of this system is investigated by using a numerical simulation. It is demonstrated that the steady-state amplitude shows nonlinear characteristics and changes remarkably with the hysteretic torque of the system. The behavior of resonance curves is examined in detail when the equilibrium point of the torsional stiffness changes. The experiments are performed to confirm the results of numerical simulations, and the experimental results agree well qualitatively with those from the simulations.
