摘要: 通过光电联合测试方法,测量了常温下直径为10、15和30mm 高能钝感炸药柱JBO-9021炸药的 定态爆速和波形,根据拟合的爆轰波阵面形状,分析了波阵面法向速度Dn与当地曲率 之间的关系。研究结 果表明,JBO-9021炸药的定态爆速随药柱直径的增大而增大,JBO-9021(w(HMX)=15%)相对JB-9014炸 药(w(TATB)=95%),爆轰波形更平坦,爆轰波非理想传播行为得到一定改进。Abstract: Byusingthephotoelectric method,thesteady-statedetonationvelocitiesandthecorrespondingwaveshapesweremeasuredfortheJBO- 9021ratestickswiththediametersof10,15and 30mm,respectively,andintheJBO-9021ratesticksthemassfractionsofTATB,HMXandF2314 were80%,15%and5%,respectively,atroomtemperature.Ananalyticexpressionwasfittedtothe wavefrontdata.Andbasedontheanalyticexpression,therelationwasobtainedbetweenthenormal velocityofthewavefrontanditslocalcurvature.Theinvestigatedresultdisplaysthatthesteady-state detonationvelocityoftheJBO-9021explosiveincreaseswiththeincreaseofthediameteroftheJBO- 9021ratestick.ThedetonationwaveoftheJBO-9021explosiveisfatterthanthatoftheJB-9014explosiveinwhichthemassfractionsofTATBandF2314are95% and5%,respectively.Consequently, thenonidealspreadcharacteristicsofthedetonationwavesweaken.
