1、优秀毕业论文摘要小文以EFP战?}-部的心川开发为研究背最，运J{』X光摄影技术、甲板挑痕试验技术、计算机科学发仿真技术，对EFP的成形机理及卡j{天关键技术进行'r较为细致的研究。本文的主要研究内容及成果足：1．提出r影响EFP成形性能的天键I捌素，并通过试验及计算模拟的分析，揭示rJ．1i同形状的药型罩形成EFl)的机理。f给J，约型罩的顶u壁厚营及球缺罩母线的曲率、#释对EFP成形性能影响的舰律。!·2．研究了起爆方式对EFP成形性能的影响。f指单点中心起爆时的起爆偏心量大于1mm便会对EFP的成形形态产生严重1i良的影响。

2、并分析r其影响规律。研究'厂均布多点同时起爆下装药的爆轰机理，进而揭示-r该起爆方式F药型罩的压垮变形规律及带翼EFP的成形机理。给出的爆轰马赫波载荷公式具有实Jij性和通用性。3．建立fEFP的成形模拟律及侵彻模拟律，为小u杼研究成果向人Li径产一ifI型号的转化提供r重要的科学依据。4．给iijrEFP对不同材质靶板侵彻的丰『j关系数，为J1j臁价材料代替}^贵的标准堤甲靶板进行科学试验提供_『可靠的参考依据。关键词：聚能装药，爆炸成形弹丸，模拟律，X光摄影，起爆，穿甲试验·_-一——_一·一‘～一一．精品参考文献资料优秀毕业
