摘　　要：该文建立了自动武器抽壳计算模型，计算出抽壳时药筒与弹膛的接触压力和抽壳阻力。并且利用应变式测力传感器，建立了自动武器抽壳测试系统，测出了抽壳力。计算与实测结果符合良好。This paper not only establishes a computing model of the extraction in automatic weapons,but also sets up an extraction measurement system.With the aid of elasto plastic finite element method and a system of revising the coefficients of loading on thematching nodal points,we have computed the extraction loads.By the experiments,wehave also measured the loads. The results of computation are in good agreement with theexperimental findings.
