| 摘要: |
| 为优化多级同步感应线圈电磁发射器性能，以提高发射速度和能量转换效率为检验指标，以影响上述指标的触发时序为优化对象，采用遗传算法建立单级同步感应线圈型电磁发射器触发位置优化数学模型，计算最佳触发位置，通过数值和有限元两种仿真系统对优化结果的正确性进行验证。采用该方法对两级以及十级同步感应线圈型电磁发射器的触发时序进行优化研究，并进行仿真验证。为解决仿真系统误差问题，提出采用动子线圈在各级的触发位置和速度作为控制因素的双控触发方式，并研究分析仿真过程中触发开关的随机抖动对出口速度误差的影响，得到最佳触发时序控制策略。 |

| Abstract: |
| To improve the performance of the SICEML (synchronous induction coil electromagnetic launcher), taking the launching speed and the power conversion ratio as the check mark, and taking the trigger sequence as the optimizing parameter, the mathematic model of Single-stage SICEML was established by using genetic algorithm. The best trigger situation was figure out. Validity of the result was confirmed by numeric and finite element analysis simulation system. In this way, a 2-stage and a 10-stage SICEML optimizing trigger sequences were approached and verified. To solve the inaccuracy problem of the emulate system, the situation and speed of armature were taken as the simultaneous qualification for switch trigger, and the effect of the activation switch′s random flutter to armature′s outlet speed was researched, and a best trigger sequence strategy is submitted. |
