Equivalence Calculation on the Initiating Magnetic Resistance Moments of the Rotating Generators for Fuzes

通过对引信用旋转发电机启动瞬间所受磁力的分析，根据其结构特点，本文提出一种切实可行的当量法来求解此类发电机的启动磁阻力矩：将其转换为计算轴承的启动摩擦阻力矩，克服了直接采用“力×力臂”进行计算所遇到的力学问题。文中给出了计算示例。

Through analyzing the magnetic force withstood by the rotating generator for a fuze at the time when it initiates, this paper puts forward a practicable equivalence calcalation method to find the mitiating magnetic resistance moment of this type of generator according to its structural characteristics, which is to transform i t into an initiating friction resistance moment , thus soling the mechanics problems met in making calculations by using the method of a force multiplying a force arm directly.
