摘要

本論文主要係以材料經過調質後，提升材料強度的觀點進行分析及評估。主要目的是針對士兵在進行衝鋒槍操演上，所面臨之槍械衝擊毀損問題加以探討，並參考過去衝鋒槍之製作材料強度，經由上述過程所產生的資訊，由其中選擇較適合作為新式衝鋒槍之輕金屬，同時進行衝鋒槍之結構分析以達到最佳設計製作，使用財團法人金屬工業研究發展中心精微成形研發處精密成形系統組，其特有之“微粒子改質處理”技術，對材料進行表面改質，同時以有限元素分析模擬衝鋒槍上節套在槍機擊發過程中所產生之應力變化，有助於衝鋒槍結構設計。論文中並分析及探討評估調質後的結果。

From the point of view of material strength, the purpose of this research is aimed to investigate the damage on gunlock impact in firing the submachine gun. The part of a gunlock is designed to hit the primer or firing pin, or explodes the percussion cap and cause the gun to fire. Compared with previous foreign developed submachine guns, an enhanced light metal, such as Aluminum alloy 6061 is suitable for an improved upper barrel extension in a newly designed submachine gun. This project is utilizes special equipment in Precision Forming System Section, Metal Processing R&D Department of Metal Industry Research & Development Center (MIRDC). The surface modification of material Al 6061 has been conducted by using the technology of Wide Peening & Cleaning (WPC) or Micro Particle Peening (MPP). Based on finite element method, the thermos-structure coupled analysis of upper barrel extension has also been performed by ANSYS. A series of experimental and simulation works are conducted to design the new submachine gun in this research.
