鉴于电磁发射试验对简易测速装置的需求,设计了一种多层锡箔靶测速系统,实现了对平面螺旋线圈电磁发射装置所发射运动板速度的实时测量。在此基础上进行了可行性发射试验和稳定性发射试验,并对试验中所测量速度的误差进行了计算和分析。试验结果表明,测速系统多次重复测量的误差小于8%,满足设计要求。

To meet the requirements of a simple speed measuring apparatus in the plane spiral coil electromagnetic launching experiment,a kind of multilayer foil target speed measuring sys-tem was designed,the system realized the real-time measurement of the speed of the active plate launched by the plane spiral coil electromagnetic launching system.Based on this,feasi-bility and stability launching experiments were carried out by use of the speed measuring sys-tem,and the errors of the measuring speeds were calculated and analyzed.The repetition ex-periment results showed that the error of the speed measuring system is less than 8%,and it can satisfy the design requirement.
