Vibration of scanning magnet for space environment simulation and research infrastructure

  • 摘要: 研究了近代物理研究所为哈尔滨工业大学(HIT)空间环境地面模拟装置(SESRI)研制的扫描磁铁的振动,通过试验,使用激光位移传感器采集扫描磁铁上关键点的振幅,对比振幅分析影响振动的因素。试验数据显示,当电流为450 A、频率小于140 Hz时,振动平缓;磁铁整体振动随输入电流频率升高与电流增大而增强,电流频率为磁铁振动的主要影响因素;磁铁内带阻尼性材料部分的振幅明显小于其他部分。同时哈尔滨工业大学扫描磁铁采用的线圈铁芯浇筑一体结构设计,振动明显减小。结论证明磁铁机构与工艺的合理设计能有效减振。
