【摘要】：针对稀土永磁材料的迅速发展,制造出吨位级的永磁吊成为一种可能和需求,本文设计并制造出一种完全不用电的依靠自动吸卸结构实现对钢铁物件进行吸卸的磁吊。本文首先研究了稀土永磁吊的工作原理及磁路设计原理,选择最适合的磁性材料,对磁路结构进行了设计,并用磁导法计算磁极面处的磁场强度及吸力的大小。其次应用有限元软件研究了在吸物状态时磁极面处的磁感应强度分布以及磁吸力的大小。应用有限元软件计算出卸物状态时的磁极面处的残余磁场强度的分布及残余磁力的值。设计出磁吊的自动吸卸结构,实现了无电的操作。设计的磁吊的自锁机构,防止了高磁能不稳定状态时可动磁系的翻转。最后制造出工业样机并进行了试验研究。试验结果表明,本文所设计的新型节能稀土永磁吊符合设计指标。
[Abstract]:In view of the rapid development of rare earth permanent magnetic materials, it is possible and necessary to produce a tonnage permanent magnet suspension. In this paper, we design and manufacture a kind of magnetic suspension which can absorb and unload iron and steel objects completely without electricity. In this paper, the working principle and magnetic circuit design principle of rare earth permanent magnet suspension are studied, the magnetic circuit structure is designed by selecting the most suitable magnetic material, and the magnetic field intensity and suction at the magnetic pole surface are calculated by the magnetic conductivity method. Secondly, the distribution of magnetic induction intensity and the magnitude of magnetic suction at the magnetic pole are studied by using finite element software. The distribution of the residual magnetic field intensity and the value of the residual magnetic force at the pole surface in the state of unloading are calculated by using the finite element software. The automatic suction and unloading structure of magnetic crane is designed to realize the operation without electricity. The self-locking mechanism of the magnetic crane is designed to prevent the rotation of the movable magnetic system in the unstable state of high magnetic energy. Finally, the industrial prototype was manufactured and the experimental study was carried out. The test results show that the new energy saving rare earth permanent magnet suspension designed in this paper accords with the design index.
