Abstract

A method for computing dynamic response considering joint dry friction has been developed based on equivalent linearization and micro-slip model. Computational simulation model was established by linking corresponding contact nodes with Matrix27 elements which simulate additional stiffness and damping effects on structure caused by dry friction nonlinear force. Equivalent stiffness and damping coefficient formula was deduced to calculate real constants of Matrix27 elements. An iterative program was created to compute maximum slip displacements of Coulomb contact nodes on interface and dynamic response and vibration stress were calculated then. An experimental verification has also been carried out which testified the accuracy of the method. Evidently attenuation of vibration is revealed which certifies the effectiveness of joint dry friction damper. Better attenuation effect occurs when exciting frequency is nearer natural frequency.
