摘　　要：该文阐明了电动振动台的磁路工作原理、持点,提出了磁路的计算思路和方法,详细推导了工作气隙的磁导、磁压降,非工作部分的磁导、磁压降和主磁动势的计算公式,讨论了影响磁路中各部分的磁导、磁压降各个参数之间的相互关系,导出了主磁动势所需要合理的激磁线圈的安匝数IW。The working principle and the characteristic of electrodynamic vibrator are described in this article. The calculation ideas and method for magnetic induction are proposed. The calculation formula of magnetic conductance and magnetic potential difference of the working air hole, and the calculation formula of magnetic conductance, magnetic potential difference and main magnetomotive force of the non-working section, are proposed in detail. The correlations between the parameters of magnetic conductance and magnetic potential difference are discussed. The rational ampere-turns of excitation coil needed by the main magnetomotive force are obtained.
