摘要: 针对JO-9C(Ⅲ)炸药的冲击起爆判据参数缺失问题，结合理论模型和模拟计算结果，拟合得到了JO-9C(Ⅲ)炸药的3种不同形式的起爆判据参数。利用AUTODYN软件，建立了不同尺寸钛飞片冲击起爆JO-9C(Ⅲ)炸药的数值模型，得到不同尺寸钛飞片起爆JO-9C(Ⅲ)炸药的临界速度。根据冲击起爆理论和飞片临界起爆速度，计算出JO-9C(Ⅲ)炸药内入射冲击波的波阵面参量，再结合p-τ、James和Π-τ 3种起爆判据形式，拟合得到JO-9C(Ⅲ)炸药的起爆判据参数，起爆判据参数的拟合精度从高到低依次为Π-τ、p-τ、James。Abstract: Aiming at the parameter missing problem of the shock initiation criteria of JO-9C(Ⅲ) explosive, parameters of three different forms of initiation criteria of JO-9C(Ⅲ) explosive were obtained by fitting the theoretical model and simulation results. The simulation models of shock initiation of JO-9C(Ⅲ) explosive with different sizes of titanium flyer were established by AUTODYN software, and the critical velocities for shock initiation of JO-9C(Ⅲ) explosive with different sizes of titanium flyers were obtained. The incident shock wave front parameters of JO-9C(Ⅲ) were calculated based on the shock initiation theory and critical initiation velocities of flyers. Combined with the three initiation criteria forms of p-τ, James, and Π-τ, the corresponding initiation criteria parameters of JO-9C(Ⅲ) explosive were fitted. The parameters fitting accuracy of the three initiation criterion from high to low is Π-τ, p-τ, James.
