| 摘 要： | "航天器上安装的精密有效载荷需要一个十分""安静""的工作环境,而作为一个主要的激振源,姿态控制飞轮产生的振动会严重影响有效载荷的工作质量.除提高飞轮的制造精度外,为飞轮设计安装隔振装置是一种较为有效的方法.本文总结了国内外针对飞轮隔振问题进行的研究工作与解决方案,讨论了被动隔振与主动隔振的优缺点,使用等效被动元件的方法分析了主动控制规律的本质,并在此基础上提出了一种使用被动元件实现主动控制规律的飞轮拟主动隔振方法.仿真计算结果表明,拟主动隔振方法能够改善被动隔振装置的性能,能够在保证高频隔振性能的同时有效衰减共振峰值."

| Abstract: | High precision payloads of a modern spacecraft require an ultra-quiet operating environment. As one of the major disturbance sources,the vibration of the reaction wheels greatly affects the performance of payloads. Besides improving the manufacturing accuracy,it is a good choice to add vibration isolators to the reaction wheels. The existing research work and solutions on flywheel vibration isolation are summarized in this paper and the characteristics of both passive and active isolation are discussed. An ... |
