摘要
首先推导了描述铁磁体的磁场方程,并分析计算了圆筒型周期性永磁结构环内部所携带的磁能,研究了磁能与永磁体质量的关系。分析表明,采用内外径分别为60和90mm、长为60mm、质量约为30kg的四级周期永磁结构能够提供1kJ左右的磁能。这种结构有可能成为间接馈电磁累积发生器的初始能源。
In a lot of single-shot applications and experiments at remote locations where magneto-cumulative generator provide the most practical pulse power, it is impracticable to use a capacitor bank as the initial energy source. V. V. Gdovnina et al has used a permanent magnet ring as the initial energy source to drive a magneto-cumulative generator, but the energy density stored in a single permanent magnet ring is very low. In this paper, the possibility of using periodic structure permanent magnetic rings as initial energy source of magneto-cumulative generator is analyzed theoretically. It is concluded that 1 kJ initial energy can be provided to magneto-cumulative generator by the periodic structure permanent magnetic ring whose mass is less than 30 kg and the outside radius less than 60 cm, and some relative technical problems are also considered.
