航天器微振動(dòng)環(huán)境分析與測(cè)量技術(shù)發(fā)展

Analysis on Micro-vibration Environment of Spacecraft and Measurement Technology

  • 摘要: 文章分析了航天器在軌運(yùn)行時(shí)出現(xiàn)的準(zhǔn)穩(wěn)態(tài)加速度、瞬變加速度、振動(dòng)加速度的來(lái)源及對(duì)航天器產(chǎn)生的影響。介紹了美國(guó)、歐空局及我國(guó)的航天器微振動(dòng)測(cè)試技術(shù)現(xiàn)狀。并就Olympus衛(wèi)星、Oicets衛(wèi)星和我國(guó)“神舟”號(hào)飛船的情況，深入討論了微振動(dòng)測(cè)試的方法與結(jié)果。

     

    Abstract: The micro-accelerations of orbiting spacecraft, such as quasi-steady acceleration, transient acceleration and vibratory acceleration, are described, and its disturbance sources and effects on spacecraft are analyzed. In addition, the micro-vibration measurement technologies are illustrated, together with the measurement methods and the results of the micro-vibration.
