| 英文摘要: |
| Barrel life of gun is the key indicator of gun's performance. The significance to increase barrel life of gun is to maintain gun's performance for a longer time with higher sustained & efficient combat capability in the life cycle on the condition of good stability of ballistic performance. The gun barrel life is described in terms of current developing status, trend and gap at home and abroad, definition & assessment criteria and the general predicting method of barrel life are put forward, the influence factors of barrel life including propellant charge, barrel materials, launching load, and gun bore surface strengthening are analysed, and those factors such as thermal effects, chemical effects, mechanical effects, and chamber pressure effects are specified. Some issues, key technologies and preliminary technical measures concerning the increase of barrel life are put forward, including gun bore chrome plating technology. The technical proposal and approaches of gun bore chrome plating technology are detailed, a target for increasing barrel life to reach the advanced international standards is set, technical development trend of increasing barrel life is pointed out, and technical reference for the study of increasing barrel life is provided. |
