Research on Reliability Evaluation Method for Fuse Based on Multi-source Information Fusion
To address the issues that,ammunition prices are expensive for full missile flight tests to verify their reliability of high value missile fuses,there is fewer target test for full missiles,and the reliability indexes of fuses are higher than those of full mis-siles.Therefore,it is necessary to make full use of the simulation test data to supplement the important data for small samples.The inherited factor and environmental factor are used to convert different types of data into the successful or failed experimental data.Then,the combined modified maximum likelihood(MML)sequential reduction(SR)(CMSR)method is used to fuse multi-source data based on the series parallel relationship of the system,and the obtained data is combined with the target experimental data to re-duce the sample size of the target experimental data.By taking the mixed Beta distribution as a prior distribution,it obtains the Bayes method for evaluating the reliability of fuses,the method solves the problem of integrating simulated test data with target test data.The reliability evaluation is conducted using a certain fuse as the application background,proving that this method reduces a certain a-mount of target field testing compared to classical methods.
