| Abstract: | 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. |
