基于爆轰产物的JWL状态方程和Taylor破裂判据,从能量守恒出发推导了一种考虑膨胀细节的爆轰驱动金属圆筒能量转换与破片初速模型.选用无氧铜、45~#钢和6061铝合金3种材料进行压装TNT炸药驱动的圆筒试验.对比试验的膨胀轨迹与膨胀速度和模型计算结果,表明所建立的爆轰驱动模型综合考虑了炸药-金属系统驱动的膨胀过程和力学性能因素,相比格尼公式只单一考虑炸药爆轰参数的驱动能力,更全面地考虑爆轰驱动影响因素,计算结果更具有针对性和适用性. |

Based on the JWL equation of state of detonation products and Taylor fracture criteria, a model considered the expansion details about energy conversion and fragment initial velocity is derived from conversation of energy. The cylinder tests of three materials, including copper, 45~# steel and 6061 aluminum alloy, driven by TNT explosive are made, and the inflation track and velocity are analyzed. The experimental results show that, by comparing with Gurney formula which is considered only to express the driving ability of the explosion parameter, the proposed model considers the driving factors, inflation process and mechanics function of meta. The result is of pertinence and applicability. |
