Load distribution in the thread of body

Abstract

This paper presents the analytical model of load distribution in the body thread. The model estimates a variation of longitudinal strains in contiguous to the body thread layer, which takes place at the receeding from the locations of the turn loads. The influence of the wall thick-ness of the cast iron body in case of this variation at unit force is assessed by FE method. Load distributions on the turns are calculated for the steel stud connections with the compressed and tension bodies of cast iron.This paper also presents the application of the proposed model to a preliminary analysis of the relation between the stability condition of the internal defect of the tension body and the tight of the connection at high cyclic loading.
