| Abstract: |
| The technical conditions of cannon barrel has close relation to the critical index of firing precision and cannon barrel life. The structure, principle, and working process of several typical cannon barrel inner diameter measuring instruments recently appeared at home and abroad were introduced, which use the radial wear of the inner chamber fixed-point as the judgment index of cannon barrel life. The relevant technical index, such as measuring range and precision were analyzed and compared. The advantages and disadvantages of these methods were introduced from the aspects of maneuverability and applicable situation. The development of inner diameter measuring instruments suitable for army application in future was put forward according to the practical need of army. |
