身管是火炮、自动武器的重要组成部分。径向锻造是一种新的制造身管的方法,相比传统的身管加工方法,采用径向锻造工艺加工身管不仅节约材料,而且使身管强度得以提高,寿命得以延长。以某身管径向锻造过程为研究对象,用三维建模软件Solid Works建立身管径向锻造的三维模型,借助金属塑性成形有限元软件Deform对身管径向锻造过程进行数值仿真模拟,分析了径向锻造过程中膛线形成时金属的流动情况,并通过试验加以验证,试验结果表明,材料在受到锻压力产生变形时,存在中性面,中性面两侧的金属材料同时存在径向和轴向的变形,与仿真结果相吻合。
Barrels are artillery, automatic weapons an important part. Radial forging is a new way to manufacture the barrel. Compared with the traditional barrel processing method, the radial forging process can not only save material, but also improve the strength of the barrel and prolong the service life. Taking a radial forging process of a body tube as the research object, a three-dimensional model of the radial forging of the body tube was established by a solid modeling software 3D, and the numerical simulation of the radial forging process of the tube was carried out by means of the Deform metal finite element software Deform The flow of metal during the formation of rifling in radial forging process was verified and verified by experiments. The experimental results show that when the material is deformed by forging, there is a neutral plane, while both sides of the neutral plane have the same radial And the axial deformation, and simulation results match.
