摘要
为了研究感应线圈发射器发射过程中的同步控制问题,设计并搭建了三级同步感应线圈发射实验装置.该装置采用一种基于仿真结果的定时控制方案:通过对驱动线圈机电模型的仿真,得出电枢在各级线圈中的最佳触发位置,进而得到在每两级驱动线圈之间的理论运动时间,并结合控制电路中信号延时,确定每两级驱动线圈之间的触发时间间隔,通过单片机设置时间间隔来实现对发射装置的控制.为了防止放电回路中的强电流对控制电路的影响,并保证人员和设备的安全,该装置还实现了控制回路与放电回路之间的光电隔离.
The experimental installation of a three-stage synchronous induction coil launcher is designed and set up in order to investigate the synchronization control during the launching process. A timing control scheme is used in this installation aecoMing to the simulation result. The best di^harge pc^sition of the arma- ture in the coil of each stage is obtained through simulation of the electromechanical model. The time of the armature parsing through coils of each two stage in theory is also gained. Time interval between two stages of coil is determined combining with the signal delay in the control circuit. Time interval is set by the microchip in order to control the launcher. The photoelectric isolators are also used to avoid the interferences to controlling circuit from the strong current in the discharge circuit.
