Abstract: Through the failure mechanism analysis and simulation test of a certain kind of detonator, this paper confirms the stress level of the stepping stress acceleration life test of the detonator, and  then establishes the data processing mathematical model and storage life forecasting method.  At last, according to the result of the stepping stress acceleration life test of the detonator, this paper forecasts the reliable storage life of the detonator under the normal stress level.

 

Key words:detonator; stepping stress acceleration life test; storage life forecast
