| The paper intends to study the change rule of electrical parameters and the failure mechanism of an electronic time fuze at ‒60~140 ℃. Through the high and low-temperature testing machine, to carry out the step stress reliability enhancement test, add and refine tested parameters, record the changes of electrical parameters in the whole process under the working condition of the tested fuze, and carry out the failure mechanism analysis. The test concluded the temperature characteristic law and parameter variation range of electrical parameters such as fuze reference frequency and power loss rate, found the fault mode and mechanism of sudden voltage drop at ‒60 ℃ and short circuit at 130 ℃, and put forward the improvement suggestions. The test verifies the intensified test method of extreme temperature stress and electric stress, obtains the change rule of fuze electrical performance parameters, and finds the new failure mode and failure mechanism under extreme temperature conditions. |
