Abstract

This paper presents results of experimental and theoretical studies on the dynamics of a bolted joint under torsional excitation. Hysteresis curves of the resultant torque versus the applied angle of twist are obtained from the experimental results. These experiments have shown relative slippages between the clamped parts and between the contact threads. Based on the experimental results, the coefficients of friction between the contact surfaces are obtained using a theoretical method. An effective modelling method is presented to exactly construct helical thread profiles. Using the finite element model thus obtained, the hysteresis curves are reproduced from the finite element analysis. Finally the hysteresis curves are recreated by a modified Jenkins element model which agrees with the detailed finite element model.
