摘要
分析了影响液压支架用本质安全型电磁铁的吸力因素,利用有限元分析软件ANSYS完成电磁铁的二维静态仿真,得出电磁铁的磁场分布及吸力特性曲线。对比仿真结果,得出相对于采用平头状的衔铁结构,采用锥头状衔铁结构的电磁铁的初始位置吸力由3.6N提高到4.5N,吸力特性曲线较平稳;减小了衔铁与线圈的径向间隙,吸力增大。
This paper analyzed the factors influencing the intrinsicaUy safe electromagnet＇s suction, and carried out 2D static simulation of the electromagnets and got the magnetic field distribution and suction characteristic curves. Results show： compared with the armature with flat-shaped structure, the armature with cone-shaped structure can increase the suction from 3.6 N to 4. 5 N, being of smoother curve of suction. The electromagnet＇s suction has increased when reduce the radial clearance between the armature and the coil.
