Abstract
Aiming at the reliability evaluation of the energy transfer interface of pyrotechnic sequence,a reliability evaluation method based on fiducial inference method was proposed.This method fully considered the randomness characteristics of the en-ergy transfer interface data.By constructing the probability distribution model of the performance parameters,the prior knowl-edge was organically combined with the test data,and the accurate evaluation and randomness quantification of the interface re-liability were realized.Firstly,the reliability model of the energy transfer interface of pyrotechnic sequence was established.On this basis,the reliability evaluation algorithm framework based on fiducial inference was designed.In order to verify the effective-ness of the proposed method,the evaluation results of the quantile correction method and the Monte Carlo method were com-pared and analyzed.The results show that when the sample size is 3 to 70,the deviation between the evaluation results based on the fiducial inference method and the true value is the smallest,demonstrating good convergence and stability.Especially when the sample size is less than or equal to 10,this method shows significant advantages,which effectively overcomes the de-pendence of traditional methods on sample amount,and provides a new method for the reliability evaluation of the energy trans-fer interface of pyrotechnic sequences.关键词
