永磁磁浮在心脏泵及其它应用中的稳定平衡

学术界一致公认无源磁浮是不稳定的，作者却找到两种实现稳定无源磁浮的方法，其一是引入非磁力，单独或者与永磁力一起，对浮体至少在一个自由度上产生作用；其二是利用浮体运动（旋转）的惯量，实现至少一个自由度上的稳定平衡，结合这两种方法，作者研制成两种不同设计的永磁磁浮心脏泵；并尝试将无源磁浮技术应用于高速列车和超静音螺旋桨。

Permanent Maglev Stability: New Concept,New Design and New Applications

It is widely acknowledged that it is impossible for permanent maglev to achieve stability. However, we have found two approaches to achieve stable permanent maglev. One is to imtroduce nonmagnetic force either alone or together with magnetic force to act on the levitator in at least one degree of freedom; the other is to use the inertia of moving (rotating) levitator to reach stability in at least one degree of freedom. Based on these two methods, we have developed two different artificial heart blood pumps with permanent maglev impellers. As examples of other applications, permanent maglev high speed trains and permanent super low noise propellers for ships and boats are also introduced.
