Abstract: | Several criteria for barrel lifetime were summarized and discussed. Based on large amount of test data,the advantages and disadvantages of the criteria were analyzed and the requirements for the easy and practical criterion were put forward. Then,a new criterion based on the radical wear at the start points of the barrel lands was proposed. The close interrelationship between the radical wear and interior ballistic characteristics was illuminated theoretically and experimentally. The research results show the great value of this criterion to solve the problem of barrel lifetime. |
