摘要

Rheinmetall Rh-120光膛砲是德國萊茵金屬研製的坦克砲，為全世界標準坦克砲。因應未來國防武器自製政策，本研究乃以該砲管自緊應力分析為研究主題，探討自緊對砲管射擊應力之影響，研究方法採用Le Duc方法及萊茵金屬公司自緊應力演算法進行推估與分析。最後獲得自緊對射擊應力與自緊百分比對射擊應力之影響結果，經由推估分析結果得到以下結論：（1）自緊預置應力抵消射擊應力使砲管皆處於安全範圍。（2）較合宜之自緊百分比為60-70%。

The Rheinmetall Rh-120 is a smoothbore tank gun developed by Rheinmetall and is recognized as the global standard. This study focuses on analyzing the autofrettage stress in the Rheinmetall Rh-120 and investigates the impact of the autofrettage stress on the barrel firing stress in response to the future national defense weapons domestic production policy. For the estimation and analysis, the Le Duc method and Rheinmetall's autofrettage stress algorithm were used. Finally, this study revealed the result of the autofrettage stress and the effect of the percentage of the autofrettage stress to firing stress. The results led to the following conclusions: (1) The autofrettage stress counteracts the creep stress, ensuring that the gun barrels remain within a safe range. (2) The appropriate percentage range for the thickness of the autofrettage is between 60 and 70%.
