利用理论与数值模拟相结合的方法对磁驱动飞片实验样品的尺寸设计进行了分析探讨,给出了横向尺寸设计的估算公式、长度设计原则、影响厚度设计的主要因素等.%Technology of magnetically driven flyer to high velocity has been developed quickly in recent years, especially at Sandia laboratory. The design of the flyer size is presented theoretically and numerically. The minimum width of the flyer is given by an equation considering the influence of rarefaction wave from flyer side. The flyer length is mainly limited by the conductance. The flyer thickness is decided by the magnetic field diffusion and the magnitude of driven current.
