炸药非理想爆轰能量释放与能量利用的关系

摘要

通过对C-J模型条件下多方状态方程的修正,得到炸药非理想爆轰过程的p-υ关系.通过典型炸药算例,讨论了在不同释能速率快慢指数(n)和释能(q)条件下,非理想爆轰膨胀功(W)的相对能量利用趋势,得出W-q与W-n的关系曲线,可为高能常规毁伤技术和战斗部设计中装药非理想爆轰的能量利用效率优化提供理论依据.%The p-v relationship of non-ideal detonation of expeosive was obtained by modified multiaspective state equation of C-J conditions.The relative energy utilization trends of non-ideal expansion work (W) were discussed with different release rate exponent (n) and different release energy (q) in typical explosive, and the relationships of W-q and W-n were obtained.The obtained results provide theoretical base for the energy utilization efficiency optimum of non-ideal detonation in conventional high energy damage techniques and warhead charge designs.
