焊接钢质药筒表面处理质量与药筒退壳性关系的研究

Study of the Relation between the Surface Treating Quality of Welded Steel Cartridge Case and Cartridge Case Ejection

对几种不同表面处理的焊接钢质药筒在退壳时所需抽壳力的大小进行了理论计算与实测对比，论证了药筒表面处理方法或质量在药筒退壳性设计中的作用，完善了焊接钢质药筒退壳性设计的理论。

Theeretical calculations and measured comparisons about drawing shell forces produced by several kinds of weded steel cartridge case tredting their surfaces when setting out of shells, demonstrdte methods of cartidge case's surfacl treating or quality functions in cartridge case ejection design, and make the theorg about welded steel cartridge case ejeetion design perfect
