Abstract

The work aims to quantitatively analyze the influence of different environmental profile orders on the reliability of automatic rifles. With a small-caliber automatic rifle as the test object, experiments were conducted in the order of normal temperature, low temperature, salt spray, high temperature, immersion water, and fugitive dust environment profiles. Failure data under different combinations of environmental profile orders were statistically analyzed, a cumulative failure prediction model within the life cycle was established, and the influence degree of different environmental profile orders on the reliability of automatic rifle was obtained through analysis. The test results showed that the number of automatic rifle failures varied significantly under different combinations of environmental profile orders, and the order of different environmental profiles had different degrees of influence on the reliability automatic rifles. Therefore, fugitive dust environment has the most significant sequential effect on subsequent profiles, while normal temperature has the least significant effect. High-temperature and low-temperature profiles are prone to being affected by other profiles.

Key words
