Numerical study of the screw-nut mouvement in the self-loosening process under transverses loading

Abstract : Self-loosening of bolted assemblies under transverse loading is an issue studied several times. A first study axis is about localized or generalized sliding, in threads. A second study axis is about kinematic and relative movement between the nut and the screw. The aim of this paper is to study those aspects by observing the behavior of a double shear assembly. Thus a numeric model, taking account of the threads, the boundaries conditions and the contacts in, has been developed. In the first instance, the macroscopic and microscopic behaviors, respectively self-loosening and localized slip, were observed. In the second instance, a study of the relative movement between the screw and the nut highlighted a tilting one from another, in accordance with the hypothesis made by Kasei. Therefore, this paper contributes to support the self-loosening process evolved by Kasei.
