Abstract

The mechanical structure of the breech block after repairing is different from the original breech block. It is assembly parts of the new front-end face, the original breech block, and the connecting screws. So analyzing the stress and deformation of the breech block is an important issue in the repair process for the breech block. The paper is focused on analyzing the stress and deformation of the breech block before and after repair using the finite element method (FEM) approach. Besides, the results of the FEM are compared with the analytical method approach. The comparison between the results of the analytical method and FEM results shows a very good agreement (before repair, the difference in maximal stress between the two methods is 2.12%). The study object of this paper is the wedge-type breechblock.
