Temperature and Humidity Accelerated Model and Modeling Technology of Initiating Device

The theoretical analysis and applicability of the commonly used life distribution model and the commonly used temperature and humidity acceleration model are discussed. The data processing and modeling methods of the temperature and humidity acceleration test of pyrotechnic products are studied, and different models and distributions of the pyrotechnic device are obtained. The acceleration factor is compared. The results show that the Peck model and Lawson model are used as temperature and humidity acceleration models, although they represent different failure mechanisms, but the acceleration coefficient and life extrapolation results are consistent. The acceleration coefficient and life calculation modules formed at the same time can provide a means for rapid calculation of acceleration coefficient.
