Abstract
A numeric simulation of an open-barrel crimping process of 7-stranded wire has been conducted using a full 3- dimensional non-linear explicit dynamic finite element model. This work concentrated on studying the effect of serrations. Three types of open barrel crimps were compared - one with 2 serrations and two with 3 serrations of different kinds. In addition, serration geometric parameters were varied. The model was validated using experimental results. The goal of the study was to investigate the effects of the number of serrations and their length, as well as serration width, depth, and the slope of serration sidewall on the quality of an open barrel crimp connection.
