摘　　要：堵驻状态下,单级同步感应线圈炮(SSICG)的电枢位置固定,电枢与线圈间的互感和互感梯度保持不变,且电磁力与线圈电流平方存在一定的线性关系。分别利用Matlab和Ansoft软件建立了SSICG电流丝等效电路模型以及有限元模型,对不同放电电压下的堵驻电磁力进行了仿真计算。最后利用实验室设计生产的SSICG样机对堵驻电磁力进行了测量,试验数据与仿真结果吻合较好,验证了电磁力与线圈电流平方的线性关系,为SSICG动态发射提供了试验基础。In the blocked state, the position of the armature of a single synchronous induction coilgun （SSICG） is fixed. Hence the mutual inductance and mutual inductance gradient between armature and coil are fixed and there is a linear relation be- tween the electromagnetic force and the square of the current of the coil. The current filament equivalent circuit model and the fi- nite element model were created by means of Matlab and Ansoft softwares respectively, and the forces of the armature at different discharging voltages were analyzed by means of the two models respectively. Finally the force was measured by the SSICG proto- type in the laboratory and experimental results show a good agreement with the simulation results. It verifies the linear relation between the electromagnetic force and the square of the current of the coil, which provides experimental basis for the dynamic launch of the SSICG.
