| In order to obtain the accurate extrapolation formula of temperature and humidity acceleration coefficient, the temperature and humidity acceleration model suitable for Initiators & Pyrotechnics and the calculation program of acceleration coefficient are studied. Through the analysis of the applicability of various two-factor acceleration models used at home and abroad, the temperature and humidity acceleration models applicable to the pyrotechnics are determined. The free and open-source statistical analysis software-R software is used to develop two temperature and humidity accelerated aging algorithms by a single set of data fitting and multiple sets of data fitting to test data obtained from an ignition head under two conditions of temperature and humidity acceleration by accelerated testing, and the accuracy of life extrapolation under three life distributions of the two algorithms is compared and analyzed. The Peck model is determined to be the temperature and humidity acceleration model applicable to Initiators & Pyrotechnics, and the temperature and humidity acceleration coefficients and the humidity term reaction rate constants corresponding to certain electric match is obtained. The temperature and humidity accelerated aging algorithm fitted to multiple sets of data is more compatible with the test data than the temperature and humidity accelerated aging algorithm based on a single set of data fitting; and among the three life distributions, the calculation results of the acceleration coefficient of the Weibull distribution are more conservative, and the life extrapolation results are more reliable. |
