首发时间:2016-05-27
摘要:应用高温超导磁悬浮技术替代现有微小推力测量台架敏感元件,有利于实现大承载、整发动机悬浮的微小推力测量台架,进而排除推进剂供给管路、供电线路的影响。高温超导悬浮摆动恢复力矩的变化规律是设计高温超导磁悬浮微推测量敏感元件的基础。通过试验研究发现单块永磁/超导悬浮的摆动恢复力矩与摆动角度呈线性关系。试验研究了超导体磁化时永磁体姿态对恢复力矩的影响。永磁体倾角与偏心距的增加都将导致恢复力矩系数的增大,场冷高度的增加可以降低恢复力矩系数。

Experimental Study of HTS Suspension Applied for Micro-thrust Measurement
Abstract:Appling high temperature superconducting magnetic levitation (HTSML) technology into micro thrust measuring sensitive element could eliminate the influence of supply pipeline and power supply line. Thus, a stand with high precision and large bearing could be designed. The change regulation of restoring torque in HTS suspension is a base for the design the sensitive cell using HTSML. A linear relationship between restoring torque and swing angle is found experimentally. Also, the effect of attitude of permanent magnet when the HTS is cooling is studied. The stiffness coefficient of restoring torque will increase with the enlarge of both of the eccentric distance and tilting angles. While there is a negative relationship between the stiffness coefficient and field cooling height.
