【摘要】：基于爆轟數(shù)值模擬計算,分析了CL-20混合炸藥爆轟反應(yīng)的特征,設(shè)計了炸藥與窗口的界面粒子速度測量實驗裝置;采用激光干涉法,測量了C-1炸藥(CL-20/粘合劑/94/6)與窗口的界面粒子速度;運用先求導(dǎo)、再分段擬合的方法,對界面粒子速度隨時間的變化曲線進行了數(shù)據(jù)處理,確定了炸藥爆轟CJ點對應(yīng)的時間位置;根據(jù)CJ點對應(yīng)的粒子速度,計算獲得了炸藥的爆轟反應(yīng)區(qū)寬度和CJ爆轟壓力。結(jié)果顯示:密度為1.943 g/cm~3的C-1炸藥的爆轟反應(yīng)時間為38 ns,CJ壓力為34.2 GPa。
[Abstract]:Based on the numerical simulation of detonation, the characteristics of detonation reaction of CL-20 mixed explosive are analyzed, and the experimental device of particle velocity measurement at the interface between explosive and window is designed. The interfacial particle velocities of C-1 explosive CL-20 / CL-20 / binder / 94 / 6) were measured by laser interferometry. By using the method of first derivation and then piecewise fitting, the variation curve of particle velocity with time at the interface is processed, and the time position of detonation CJ point is determined. The particle velocity corresponding to the CJ point. The detonation reaction zone width and CJ detonation pressure were calculated. The results show that the detonation reaction time of C-1 explosive with a density of 1.943 g / cm ~ (-3) is 38 ns. CJ pressure was 34.2 GPa.

【正文快照】： CL-20炸藥爆速快,爆壓高,但爆轟反應(yīng)時間短,這給觀測其爆轟波結(jié)構(gòu)帶來困難。采用激光干涉法觀測炸藥與窗口的界面粒子速度,是分析炸藥爆轟波結(jié)構(gòu)的主要方法之一。該方法把界面粒子速度隨時間的變化與ZND爆轟模型中的壓力分布假設(shè)相對應(yīng),將速度曲線中出現(xiàn)的速率變化折點看作爆，
