Abstract：

In order to promote the development of intelligent manufacturing for ammunition and improve the manufacturing level of ammunition, for the deep drawing process of small caliber brass cartridge case, its optimal simulation method and structure parameters combination were studied, and based on the cupping test which is similar to deep drawing process, the finite element models of different simulation methods were established by finite element platform ABAQUS. Then, the impact pressure-displacement curves were calculated and compared with the test results, and the best simulation method of the deep drawing process for cartridge case was two-dimensional statics. Furthermore, based on the two-dimensional statics, three main structural parameters in the deep drawing process for cartridge case, such as die arc radius R, die cone angle α and sizing band length H, were studied. And combined with orthogonal test, the influences of the structural parameters on the process quality were obtained,and the optimized combination of structural parameters was confirmed that R=7 mm, α=13.5° and h=3 mm, which provided reference for the subsequent studies on the intelligent manufacturing of amunition.
