【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。更多还原

【Abstract】 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 1kJ initial energy can be provided to magnetocumulative generator by the periodic structure permanent magnetic ring whose mass is less than 30kg and the outside radius less than 60cm, and some relative technical problems are also considered. 更多还原
