摘要
在温度为60℃、相对湿度为95%的加速老化试验条件下,对某火工品的单发作用时间变化情况进行了研究。研究结果表明,随着老化时间的延长,其单发作用时间均值也延长,且在加速老化21天、35天和45天,被测样品的单发作用时间最大值呈线性增长;当加速老化到56天,该火工品被测样品的可靠度降低为98.98%,当老化到67天,其可靠度降低为15.06%。
The change of an initiating device＇s function time was studied by accelerated life test at 60 ℃,and relative humidity 95%.Results show that the mean value of the detonator＇s single function time prolongs when the time of life test continues.And at the ageing time of 0,21,35 and 45 days,the maximum value of function time and the ageing time have good linear relatiouship.The reliability value of the tested sample falls to 98.98% when the ageing time is 56 days,and falls to 15.06% when the ageing time is 67 days.
