圆筒实验数据研究高能炸药的爆轰特性

摘要

根据圆筒实验数据,采用新方法计算了HMX、RDX、PETN、TNT等炸药的爆轰能,研究了爆轰产物的加速能力,并与CHEETAH的计算结果进行了对比.通过爆轰波在柱壳水介质中传播的圆筒实验方法,预估了炸药的爆压.利用实验和热化学计算的结果推导了JWL状态方程的待定常数,并依据JWL等熵线计算了做功能力.%New methods to calculate the acceleration ability of detonation products and the detonation energy of explosives with the cylinder expansion test data were applied to determine the performance characteristics for some high explosives of military interest. The obtained results were also compared to the calculation results with CHEETAH code. Moreover, the detonation pressure for chosen explosives was evaluated on the basis of a variation of the cylinder test in which a cylindrical water layer was loaded by detonation wave propagating along an explosive charge confined by the water envelope.Results of the tests and thermochemical calculations were used to deduce constants of the JWL equation of state. Finally,the JWL isentropes obtained were applied to calculate the theoretical expansion work of detonation products.
