The Step Stress ALT and Data Processing of the Radio Fuze under the Condition of Three-parameter Weibull Distribution

The scheme and data of the timing cut end stepstress ALT of a certain type of domestic radio fuze is introduced in this paper. And the unified form of the reliability distribution at each test stress level is given under the condition of three parameter. Weibull Distribution. This paper sets up the mathematics model which uses a maximum likelihood method to do shape parameter and accelerated parameter point estimation, and utilizes a simulating Newton method to find solutions according to the test data of the fuze.
