摘要
采用赤道作图法等常规磁矩测试方法无法实现磁力矩器在热真空、热循环等空间环境模拟试验过程中的磁矩监测。针对这种情况,文章提出了一种通过磁通反演磁矩的测试方法。该方法通过建立磁力矩器的磁矩与通过测试线圈的磁通之间的对应关系数据库,进而根据测得的测试线圈内的磁通值来间接地得到磁力矩器的磁矩值,从而实现了磁力矩器在高低温变化环境下的磁矩实时测试。
The traditional methods of magnetic torque measurement for magnetorquer can not be used under high-low temperature environments.In this paper,a new measurement method is proposed,in which the magnetic torque of magnetorquer is indirectly obtained by the relationship between the magnetic torque of the magnetorquer and the magnetic flux of the testing coil,to realize a real-time measurement of magnetic torque under high and low temperature environments.
