Based on current filament method, the model of multistage synchronous induction coil launcher is established. The model considers the coupling effects between the drive coils, between the drive coils and each piece of armature, and between each piece of armature. In addition, in the launching process, the effect of drive coil and armature resistance and inductance generated by skin effect, magnetoresistive effect and current heating effect are taken into consideration. Finally, the 5-stage synchronous induction coil launcher is designed and manufactured. Dynamic launch experiments are designed to verify the correctness of the model. © 2022 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.

多级同步感应发射器机电模型研究

基于电流灯丝法，建立了多级同步感应线圈发射器模型。该模型考虑了驱动线圈之间、驱动线圈与每个电枢之间以及每个电枢之间的耦合效应。此外，在发射过程中，还考虑了驱动线圈和电枢电阻以及集肤效应、磁阻效应和电流加热效应产生的电感的影响。最后设计制造了5级同步感应线圈发射器。动态发射实验旨在验证模型的正确性。© 2022 日本电气工程师学会。由 Wiley Periodicals LLC 出版。
