研制了一种磁力弹簧，它由直径大小不同的两个磁环同轴同向排列，其中一环固定，另一环可轴向滑动，组成磁力弹簧。在磁场作用下，两环自动保持一定的轴向间隙，任何外力作用下此间隙的改变会产生一个恢复力，即弹力。与机械弹簧相比较，磁力弹簧不仅节省金属材料，而且具有稳定性好及振动噪声小等优点。弹性分析显示，磁力弹簧的弹力随位移变化的线性相当好，弹性大小和可压缩位移取决于大、小磁环的直径及两者之差和磁环的轴向高度。
Developed a magnetic spring, which by the diameter of the two different magnetic ring coaxially arranged in the same direction, one ring is fixed, the other ring can be axially slid to form a magnetic spring. Under the action of the magnetic field, the two rings automatically maintain a certain axial gap. Any change of this gap caused by external force will produce a restoring force, that is, elastic force. Compared with the mechanical spring, the magnetic spring not only saves metal materials, but also has the advantages of good stability and small vibration noise. The elastic analysis shows that the elastic force of the magnetic spring changes linearly with displacement very well. The elastic size and compressible displacement depend on the diameters of the large and small magnetic rings and the difference between them and the axial height of the magnetic ring.
