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。
It is impossible to realize the magnetic moment monitoring of the magnetic torque converter in the thermal environment simulation test such as thermal vacuum and thermal cycle using the conventional magnetic moment test method such as equatorial mapping. In response to this situation, the paper presents a test method of magnetic moment inversion using magnetic flux. In the method, the magnetic moment value of the magnetic moment device is indirectly obtained by establishing the database of the correspondence between the magnetic moment of the magnetic moment device and the magnetic flux passing through the test coil, and then according to the measured magnetic flux value in the test coil Magnetic moments in the high and low temperature changes in the magnetic moment of real-time test.
