Accelerated Life Test Specification and Method on Predicting Lifetime on Machinegun

Abstract

According to active defining methods in national military performance test standard on fire arms, the whole lifetime shooting method is usually used in firearms life test, with a long time and consumes plenty of ammunitions. In order to reduce amount of test bullets and innovate life test methods, a lot of life tests research and data analysis on fire arms were conducted, and the main factors that influence on machinegun lifetime were decided, the research scheme of accelerating life test and of life parameters testing scheme were designed, equality between life in normal temperature and comprehensive life in normal, high and low temperature was verified, the accelerated life test specification, modeling scheme, life predicting and evaluating method on machinegun were proposed. The research shows that the amount of ammunitions using can be reduced about 70 percent in a life test on machine guns, life test cycle can be cut down drastically and the precision predicting life can be up to 90 percent above.
