卫星整星充、退磁机理研究

文章从理论上阐述了卫星整星充、退磁的机理,对其中地磁场环境中退磁与零磁场环境中退磁的差别,地磁场环境中退磁的时效性,退磁频率、波形、幅值以及周期与退磁效果的关系,磁波形与退磁效果的关系,不同材料、不同尺度的情况下退磁的效果,充磁试验与地磁场环境中材料的充磁的差别以及卫星整星充、退磁试验中退磁场的选取等问题进行了详细的理论分析,对于卫星整星充、退磁试验技术有指导作用。

RESEARCH ON MAGNETIZING AND DEMAGNETIZING MECHANISM OF SATELLITES

This paper expounds magnetizing and demagnetizing mechanism of satellites theoretically,including the difference of magnetizing and demagnetizing results between in the geomagnetic field enviroment and in the zero-magnetic field environment,the demagnetizing aging in the geomagnetic field environment,the relationship between demagnetizing frenquency,waveforms,amplitude,period and the demagnetizing effect,the relationship between demagnetizing waveforms and the demagnetizing effect,the demagnetizing effect for satellite's components with different material and different size,the choosing of demagnetizing field for the satellites magnetizing and demagnetizing test.
