【摘要】：南極天文望遠(yuǎn)鏡長(zhǎng)期工作在無人值守的南極之巔,每年只有一次科考維護(hù)的機(jī)會(huì).其光機(jī)電系統(tǒng)復(fù)雜且維護(hù)不易,需要科考隊(duì)員是多面手,故南極望遠(yuǎn)鏡的可靠性必須引起格外重視.基于南極赤道式天文望遠(yuǎn)鏡AST3-3(Antarctic Schmidt Telescopes 3-3)主軸控制系統(tǒng)的故障機(jī)理和故障模式,引入故障樹分析(Fault Tree Analysis,FTA)方法,得出該系統(tǒng)底事件結(jié)構(gòu)重要度大小順序.在此結(jié)果之上,易于發(fā)現(xiàn)系統(tǒng)潛隱問題和薄弱環(huán)節(jié),為提高系統(tǒng)穩(wěn)定性和優(yōu)化系統(tǒng)設(shè)計(jì)指明方向.
[Abstract]:The Antarctic Telescope has long been on the unattended top of the South Pole, with only one chance a year for scientific maintenance. The photoelectromechanical system is complex and difficult to maintain, so the reliability of Antarctic Telescope must be paid more attention. Based on the fault mechanism and fault mode of the spindle control system of Antarctic Equatorial Telescope AST3-3(Antarctic Schmidt Telescopes 3-3, the fault tree analysis method of Fault Tree Analysis (FTAA) is introduced, and the order of importance of the bottom event structure of the system is obtained. Based on the results, it is easy to find the hidden problems and weak links of the system, and point out the direction for improving the stability of the system and optimizing the design of the system.
