摘　　要：卫星多载荷转动部件工作态下,磁性呈多极化形态,产生动态磁场。多个动态磁场叠加后,会导致卫星整器各向磁矩发生周期性变化,即磁矩波动。磁矩波动的振幅取决于各器载转动部件的数量、转动频率、固有磁矩大小以及载荷工作电流。文章以某遥感卫星动态磁场数据为模型,通过测试分析卫星整星及主要转动部件的磁场和磁矩,掌握了卫星及转动部件单机动态磁场的变化规律和特征,揭示了动态磁场导致磁矩波动的原因。研究成果可为类似多转动部件遥感卫星的磁性设计和控制提供参考。Under operational conditions,rotating parts in satellites under multiple loads exhibit a multipolarized magnetic state,generating dynamic magnetic fields.The superposition of these fields results in periodic fluctuations in the magnetic moments of the satellite’s entire structure.The amplitude of these fluctuations depends on factors such as the number,rotational frequency,intrinsic magnetic moment,and operating current of each rotating part.Through analysis of dynamic field data from a remote sensing satellite,and testing and analysis of the magnetic fields and moments of the entire satellite and its main rotating parts,the variation patterns and characteristics of the fields generated by individual parts were identified.This reveals the reasons behind the fluctuations in magnetic moment.These findings offer insights for the magnetic design and control of remote sensing satellites with multiple rotating parts.
