多爆炸成型弹丸性能参数灰关联分析

Grey Relation Analysis of the Performance Parameters of Multiple Explosively Formed Penetrator

为了获得各参数对多爆炸成型弹丸毁伤性能的影响程度,以EFP速度和MEFP发散角为参考序列,以药型罩和装药参数为比较序列,运用灰关联理论对影响MEFP毁伤性能的参数进行了灰关联分析。在此基础上,应用灰关联分析结果完成了MEFP战斗部优化设计。结果表明:在较少样本空间前提下,采用灰关联理论可以分析获得影响多爆炸成型弹丸毁伤性能的各因素主次关系,而且经过优化后的MEFP战斗部,大大地提高了EFP的集聚性和毁伤性能。

In order to obtain the influence of various parameters on the damage performance of explosively formed penetrator, grey relation analysis on performance parameters of EFP is conducted by grey theory, taking EFP velocity and divergence angle of MEFP as the reference sequence, and liner and charge parameters as the compare sequence. On this basis, the optimal design of MEFP warhead is completed by use of the gray relational analysis. The results show that the primary and secondary relationship of factors influencing the damage performance of explosively formed penetrator is analyzed in the less sample space,In addition, the optimized MEFP warhead can greatly improve the clustering and damage 10erformance of EFP warhezcl.
