摘要
建立了自动武器中的抽壳计算模型。应用弹塑性有限元分析理论和配点载荷系数修正法,得到弹膛和药筒在火药燃气作用下的变形,求出了药筒与弹膛之间的接触压力和抽壳阻力。与实验结果比较,符合良好。
Establishs a model for the computation of the process of extraction in automatic-weapons. With the aid of the axissymmetric, elasto-plastic finite-element method and a system of revising the coefficients of loading on the matching nodal points, deformation of the barrel and of the cartridge case under the breech pressure can be obtained and thus the engaging loads between the barrel and the cartridge case, thereby the extraction loads computed. The results of computation agree well with the experimental findings.
