为了进一步研究主动电磁装甲防护系统中拦截板的发射过程,介绍了拦截板电磁发射原理,并给出了物理结构模型,采用有限元分析软件Ansoft对发射过程中拦截板的受力和磁场变化情况进行动态仿真,并在试验中使用脉冲功率装置作为拦截板发射装置的供电系统,利用电阻应变片和弹性悬臂梁对拦截板所受电磁力进行测量,并将仿真与试验结果进行了比较,仿真结果与试验结果基本符合。通过对拦截弹所受电磁力的分析发现,如果驱动线圈加固外壳使用铁磁材料,则会对放电电流达到峰值的时间产生一定影响,这对于研究拦截板在发射过程中的受力情况具有十分重要的意义。
In order to further study the launching process of the intercepting plate in the active electromagnetic armor protection system, the electromagnetic emission principle of the intercepting plate is introduced and the physical structure model is given. The finite element analysis software Ansoft is used to analyze the force and the magnetic field change of the intercepting plate during the launching process In the experiment, the pulse power device is used as the power supply system for the launch pad of the intercepting plate. The electromagnetic force of the intercepting plate is measured by using the strain gauges and elastic cantilever beams. The simulation and test results are compared and the simulation The results are in good agreement with the test results. Through the analysis of the electromagnetic force of the interceptor, it is found that the use of ferromagnetic materials in the shell of the drive coil will have an impact on the peak discharge time, which is very significant for studying the force of the intercepting plate in the launch process Significance.
