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.
