4. A Study on Hydraulic Autofrettage Gun Tube Dynamic Stress by Finite Element Analysis

Gun tube dynamic strength design, first of all, is to enable the identification of dynamic stress on each section of tube, and the dynamic stress calculation in analytical method or numerical method is relatively complex. For most non mechanical professional design staff, the use of finite element soft- ware interactively in the general structure of the model has certain difficulty. Therefore, the realization of gun tube dynamic strength design is an urgent need to develop a general engineering program, so that the designer can easily use this program to achieve the dynamic stress on every section of tube, and truly realize the dynamic strength design of tube. With the APDL language of ANSYS finite element analysis software platform, a suitable program for tube dynamic stress calculation procedures is developed. This program provides an engineering foundation to realize the tube dynamic strength design.
