【摘要】：為研究RDX基PBX炸藥的做功能力并確定其爆轟產(chǎn)物的JWL狀態(tài)方程參數(shù),對(duì)RDX基PBX炸藥和TNT炸藥進(jìn)行φ50mm標(biāo)準(zhǔn)圓筒實(shí)驗(yàn),獲得了圓筒膨脹位移和速度的時(shí)程曲線,對(duì)比得出RDX基PBX炸藥的做功能力明顯高于TNT炸藥;基于能量守恒對(duì)實(shí)驗(yàn)數(shù)據(jù)進(jìn)行非線性擬合,得到2種炸藥爆轟產(chǎn)物的JWL狀態(tài)方程參數(shù)。TNT炸藥的擬合參數(shù)和通過(guò)AUTODYN軟件計(jì)算得到的結(jié)果符合較好;將采用上述方法得到的RDX基PBX炸藥爆轟產(chǎn)物JWL狀態(tài)方程參數(shù)用于數(shù)值模擬,計(jì)算結(jié)果與實(shí)驗(yàn)值吻合較好,符合數(shù)值模擬標(biāo)定JWL狀態(tài)方程參數(shù)的要求。
[Abstract]:In order to study the work capacity of RDX based PBX explosives and determine the JWL equation of state parameters of their detonation products, the 蠁 50mm standard cylinder experiments of RDX based PBX explosives and TNT explosives were carried out. The time history curves of the expansion displacement and velocity of the cylinder are obtained. The results show that the work capacity of the RDX based PBX explosive is obviously higher than that of the TNT explosive. Based on conservation of energy, nonlinear fitting of experimental data is carried out. The JWL equation of state parameters of two detonation products. The fitting parameters of TNT explosives are in good agreement with the results calculated by AUTODYN software. The JWL equation of state parameters of detonation products of RDX based PBX explosives obtained by the above method are used in numerical simulation, and the calculated results are in good agreement with the experimental values. It accords with the requirement of numerical simulation to calibrate the parameters of JWL equation of state.
