摘要
简述了79式7.62mm冲锋枪的主要机构及工作原理,统计实验数据并对其故障形式进行了总结分析;对79式7.62mm冲锋枪的平均寿命进行了计算,并基于FTA法对79式7.62mm冲锋枪进行可靠性分析。经计算79式7.62mm冲锋枪平均寿命为4251发;完成4000发射击的可靠度为0.696,单发可靠度为0.989,具有较高的可靠度。
Described the main mechanism and the working principle of 79 type 7.62 mm assault rifle gun and analyzed the failure form by summarizing the experience data; The average life expectancy of type 79 7.62 mm assault rifle gun was calculated, and based on the FTA method to reliability analysis of the type 79 7.62 mm assault rifle gun. By the calculation, The average life ex- pectancy of type 79 7.62 mm assault rifle gun is 4 251 rounds; The reliability of 4 000 shoots completed is 0. 696. The reliability of single shot is 0. 989. This gun has a high reliability.
