Optimum launch control strategy of multi-level induction coilgun

基于电路理论,建立了多级感应线圈炮数学机电控制模型;分析了电枢受力的影响因素,结果表明,电枢受力决定于驱动线圈和电枢的电流大小和它们之间的互感梯度。总结了多级同步感应线圈炮设计原则,根据设计原则,提出了感应线圈炮的最优发射控制策略,并从理论上证明其可行性,最后以10级线圈炮为例,归纳了多级感应线圈炮的触发公式,并进行了实验验证,其结果表明,通过修正触发公式,仿真结果与测量值吻合较好。

Based on circuit theory, an electrical mathematical model of multi-level induction coil gun is established. The in- fluencing factor of armature force is analyzed. The results indicate that the armature force is determined by the drive coil and the armature current and the mutual inductance gradient. Principle of designing multi-level induction coil gun is presented. According to the principle, the optimum launch control strategy of induction coil gun is presented, and is approved practicable by theory. At last, taking ten level induction coilgun as an example, trigger formula of multi-level induction coilgun is presented, and experi- ments are done to verify the calculation method. Amending the trigger formula, the simulation results agree well with the experi- mental results.
