| Abstract: |
| The work aims to establish a temperature and humidity two-factor accelerated life test method to obtain the temperature and humidity acceleration coefficient of pyrotechnics. By designing the accelerated life test of three kinds of pyrotechnics under different temperature and humidity acceleration conditions, regular sampling for performance test, the temperature and humidity acceleration coefficient and humidity term reaction rate constant of the three fire products are calculated based on the obtained performance data and selected temperature and humidity acceleration model, and the formula of the temperature and humidity acceleration model was determined. The temperature and humidity acceleration coefficient and humidity term model parameters of three kinds of pyrotechnics were obtained, and the temperature and humidity two-factor accelerated life test method of pyrotechnics was preliminarily established, and the next research direction was prospected. The established two- factor accelerated life test method of temperature and humidity of pyrotechnics can be extrapolated from the high-temperature and high-humidity accelerated test time to the storage time of normal temperature and humidity, which is suitable for the life prediction of pyrotechnics with poor sealing or sealing failure and high storage environment humidity. |
