【摘要】：可靠性及剩余壽命分析是基于狀態(tài)的系統(tǒng)維護(hù)(CBM)的基礎(chǔ),具有重要的指導(dǎo)意義。目前對(duì)部件級(jí)壽命預(yù)測(cè)的研究比較成熟,但對(duì)系統(tǒng)級(jí)壽命預(yù)測(cè)的研究甚少。本文基于動(dòng)態(tài)故障樹(shù)對(duì)動(dòng)量輪備份系統(tǒng)進(jìn)行可靠性及壽命預(yù)測(cè)分析,對(duì)現(xiàn)有文獻(xiàn)中備份部件失效概率密度的描述方法進(jìn)行了改進(jìn),以滿(mǎn)足當(dāng)t→∞時(shí)累積失效概率和等于1,并將改進(jìn)后的部件失效概率密度描述方法結(jié)合離散時(shí)間貝葉斯網(wǎng)絡(luò)(DTBN)對(duì)備份門(mén)的求解進(jìn)行了分析。最后,以動(dòng)量輪備份系統(tǒng)為實(shí)例進(jìn)行可靠性及壽命預(yù)測(cè)分析。
[Abstract]:Reliability and residual life analysis is the basis of CBM (system maintenance system based on state) and has important guiding significance. At present, the research on component life prediction is mature. However, there is little research on system life prediction. In this paper, the reliability and life prediction analysis of momentum wheel backup system based on dynamic fault tree is carried out. The method of describing the failure probability density of backup parts in the existing literature is improved to satisfy the requirement of t. 鈫扵he cumulative failure probability sum of 鈭，
