| 摘 要： | 为了优化磁路的设计、更好地完善方坯电磁制动理论，建立了方坯电磁制动磁场计算的数学模型，开发了计算可靠、适用性强，能适应不同尺寸磁铁的方坯磁场计算程序。通过数值模拟阐明了方坯电磁制动磁路内三维磁场的分布特点。列出了全部电磁参数和结构参数共8个因素，找出影响磁场因素的主次顺序，得到与最大磁感应强度对应的较好的磁路配置条件，讨论了操作条件对磁场的影响规律，并得到了工作间隙中心点处磁感应强度的无量纲关联式。

Numerical Simulation of Level Magnetic Field for Billet |
| |
| Abstract: | In order to make magnetic circuit more compatible, the mathematical model of LMF (Level Magnetic Field) for billet was proposed, and the billet calculating software for LMF in different magnetic circuits were developed, which are very compatible. The distribution of magnetic field in the whole magnetic circuit was given by numerical simulation. Furthermore, the better composition of billet and major factor affecting magnetic field were found by the orthogonal experiment. The effects of electromagnetic parameter and structure parameter on the magnetic field were discussed. The relation between magnetic value, electromagnetism parameters and structure parameters was given by dimensional analysis. |
