热变形纳米晶永磁环自锁阀锁闭特性研究

Latch characteristic of nano Nd-Fe-B magnet-ring latching valve

为了减轻宇航推进系统用自锁阀的重量,采用理论、数值仿真和试验相结合的方法对永磁环材料进行了研究。研究结果表明,和传统材料相比,新型永磁材料在性能上更优,装上新型永磁材料的自锁阀的锁闭特性有很大程度的优化,而且自锁阀的体积更小、重量更轻。

In order to lighten the weight of latch valve used in spacecraft propulsion system,the research is done on new nano Nd-Fe-B magnet by using theoretical,numerical and experimental methods.The result shows that the new nano Nd-Fe-B magnet has better performance than the old one.The latch characteristic of the latch valve made by the new magnet material has great superiority.Therefore,the latching valve can be more compacted and lighter.
