摘要/Abstract

摘要： 利用电磁驱动技术可模拟引信发射过程中的高过载环境，但其工作过程中产生的磁场会对被试引信产生不利影响，因此需对被试引信采取电磁防护措施。介绍了电磁驱动式引信过载试验装置的组成和工作原理，设计了被试引信电磁屏蔽罩的结构；构建了电磁驱动式引信过载试验装置的仿真模型，对比分析了不含屏蔽罩、含铝制屏蔽罩、铝钢复合屏蔽罩下引信区域的磁场强度。研究结果表明：在1 ms时刻，在不含屏蔽罩、含铝制屏蔽罩、含铝钢复合屏蔽罩3种情况下，被试引信处的最大磁场分别为1.54 T、0.17 T、4.2×10^-5 T，铝钢复合材料防护罩对被试引信具有更好的防护效果。

Abstract: The electromagnetic driving technology can be used to simulate the high overload environment in the process of fuze launching, but it may stimulate magnetic field, which has negative effects on the test fuze. Thus, it is necessary to take the electromagnetic shielding measures for test fuze. The structure and working principle of the overload experiment device for fuze based on electromagnetic driving is introduced, and then the electromagnetic shielding cover for test fuze is designed. A simulation model is established for fuze overload experiment device based on electromagnetic driving, and then the intensity of magnetic field in fuze is analyzed at three occasions: without shielding cover, shielding cover made by aluminum, shielding cover made by aluminum and steel. The results show that the maximum magnetic field in fuze is 1.54 T, 0.17 T and 4.2×10^-5 T at the occasions mentioned above, respectively, which means that the shielding cover made by aluminum and steel has better shielding performance.
