2023年5月第3期《大型铸锻件》HEAVYCASTINGANDFORGINGMay2023No.330CrNi3MoV高强锻件厚度和层数对抗侵彻性能的影响规律研究刘旸刘宝龙周峤邢春鹏(北京航天发射技术研究所,北京100076)摘要:针对一种新研的30CrNi3MoV高强钢锻件,研究锻件靶板结构对抗侵彻性能的影响,采用LS⁃DYNY有限元计算软件,对侵彻弹侵彻不同厚度、不同层数的30CrNi3MoV锻件靶板过程进行了数值计算,得到了锻件靶板的侵彻深度,获得了厚度和层数对锻件靶板抗侵彻性能的影响规律。计算和试验结果表明,30CrNi3MoV高强钢锻件具有优异的抗侵彻性能;在锻件靶板不被贯穿的极限厚度以上,单层30CrNi3MoV靶板抗侵彻能力随厚度增加而提高,与靶板厚度基本呈正比例关系;在靶体总厚度一定的情况下,多层30CrNi3MoV靶板层数越多,靶体的抗侵彻能力越弱。关键词:30CrNi3MoV;高强钢锻件;抗侵彻性能中图分类号:TJ413文献标志码:AStudyontheInfluenceRuleofThicknessandLayersNumberof30CrNi3MoVHighStrengthForgingsonAnti⁃penetrationPerformanceLiuYang,LiuBaolong,ZhouQiao,XingChunpengAbstract:Aimingatanewlydeveloped30CrNi3MoVhighstrengthsteelforging,theinfluenceoftheforgingtargetstructureontheanti⁃penetrationperformancehasbeenstudied.TheLS⁃DYNYfiniteelementcalculationsoftwarehasbeenusedtonumericallycalculatethepenetrationprocessof30CrNi3MoVforgingtargetwithdifferentthicknessanddifferentlayers.Thepenetrationdepthoftheforgingtargethasbeenobtained,andtheinfluenceruleofthicknessandlayernumberon...
