摘要伴随着科学技术的发展,强磁场在各种研究领域内的应用也越来越广泛。由于脉宽的差异,一般来说,强磁场可以分为两类,即稳态强磁场和脉冲强磁场,与之相对应的强磁场产生装置分为稳态强磁体和脉冲强磁体两类。后者由于分析设计相对比较简单、成本相对较低、操作更容易和维护简单等因素而迅速发展起来,目前已经在物理、化学、生物、医学、军事以及工业等研究领域得到了广泛的应用。76673

Title The study of the relationship between the structure of Strong magnet and Magnetic induction intensity distribution
Abstract With the progress of science and technology, High Magnetic Field (HMF) has applied in more and more scientific research field now。 Differing in the pulse width, HMF can be classified as steady-state one and pulsed one, which are generated by steady-state magnet and pulsed magnet, respectively。 As the latter one is relatively easier for manufacturing, operating and maintaining, it is much more expendable, and can be used at the field levels closed to the limit where the coil is destroyed to obtain the highest magnetic field。 Accordingly, Pulsed High Magnetic Field (PHMF) has been widely used in physics, chemistry, life sciences and so on。
The paper is around the application of PHMF in high explosive anti-tank cartridge。 The emphasis is focused on the analysis、the design、the numerical simulation、the structure optimization of PHMF。 The author designed the six kinds of HFMs which has different structure, uses software of Ansoft Maxwell to make some emulation to that。 And then analyzed the results include the HMF of different tiers、the HMF of different shapes、the HMF of abnormal shape in the same stimulation and the HMF of same tiers in the different stimulation。 And the simulation results are verified by theoretical calculation。
