摘要
动量轮、CMG等高速转动部件是影响卫星稳定性的重要干扰源。随着空间分辨率的提高和积分时间增加,扰振对成像质量的影响也越大,因此减小扰振是高轨高分辨率光学遥感卫星的关键设计内容之一。目前国内外提出了多种有效的解决途径和实施方案,从设备布局的角度讨论了减小静不平衡扰振的解决思路和策略。通过优化和仿真,分析结果表明,对高速转动部件的优化布局可减小静不平衡扰振的影响。
Momentum wheel,CMG etc high speed rator-equipmentsareimportantnoiseoriginswhich haveabadinfluence on inorbit satellite stability.As space resolution raisingandexposuretimeincreasing,disturbance influence become greater to image qulity,so reducing disturbance of high speed rotor is one of key design items for high-resolution optical remote sensing satellite on GEO robit.Currently multiple effective schemes have been presented to solve the problem by researchers,astrategy is discussed and proposed to reducing disturbance resulting from static unbalance base on rotor-equipment layout.With optimization and stimulation,theresults show that the method is valid to reducing disturbance from static unbalance by using layout optimization.
