Abstract


This paper is mainly of a spaceborne antenna system for fuzzy reliability analysis, write the part of the fuzzy reliability analysis of application software for the module. First of all, using the theory of fuzzy fault tree (FFTA), in reference to the antenna, on the basis of conventional reliability data for the star loaded antenna system for fuzzy reliability analysis. Through quantitative calculation of example, the top event is given and some key events among the probability of the interval number. Secondly, the use of mechanical structure of the reliability analysis methods, to the star in the loaded antenna deployable structure system some key events has carried on the analysis of fuzzy reliability; Threshold is given in the membership function for a certain value of lambda, corresponding to the events of the fuzzy reliability index; Possible degrees obtained the corresponding event structure failure. Finally, on the basis of the fuzzy reliability analysis, using the C Builder6.0 programming tools, wrote in the loaded antenna system fuzzy reliability analysis of application software, consists of two modules: the fuzzy fault tree analysis software module; Part of the bottom events of fuzzy reliability analysis software modules.
