通过对某型超期贮存弹药的单基发射药进行静态抗压强度试验,得到不同贮存年限发射药的抗压强度.利用可靠性理论和方法,对试验结果进行统计分析,得出超期贮存单基发射药的抗压强度随时间的变化规律.建立了基于性能老化量分布规律的发射药使用可靠性计算模型,对7/14单基发射药使用可靠性进行了预估.结果表明,随着贮存时间的增加,发射药的使用可靠性显著降低;在不同的压力波条件下,发射药的安全使用寿命相差较大.

The compressive strength of different storage age propellants of certain ammunition in excess stockpile was obtained by a static state compressive strength test. The results were analyzed by theory and method of reliability. The change rule of compressive strength of the propellant in excess stockpile with time was obtained. A service reliability model of the propellant based on distributing of capability aging quantity was established. The service reliability of 7/14 single base propellant was predicted. The result indicates that the service reliabilities of the propellant fall obviously with the storage aging. The safe service life of propellant is different under condition of different press wave.
