MODEL FOR CLOSURE OF JOINT CONTAINING WAVINESS IN THE SURFACE MORPHOLOGY

The closure behaviors of joint depend on the characteristics of composite morphology of joint principally and not morely depend on the morphologic characteristics of individual joint surfaces.In this paper after analysis of morphologic topographic characteristics of joint surfaces and composite morphology of joint a closure model for containing waviness in surface morphology is put forward.The composite morphology parameters of joint adapted in the model can reflect the influence of contact state and initial aperture on closure behavior of joint.It is confirmed by experiment that this closure model is closer to experiment results than the model that does consider the waviness in morphology of joint surfaces.
