By combining experimental tests and numerical simulations, the output pressure of JO-9c explosive was measured for a series of small-sized charge diameters, and qualitative rules and a quantitative model were obtained for the influence of charge diameters upon the JO-9c explosive output pressure. Results show that a small-sized charge diameter has a significant influence on the output pressure; in addition, the closer the charge diameter gets to the JO-9c critical diameter, the greater is the effect. The limiting diameter of JO-9c is 5 mm, and the critical diameter is approximately 0.34 mm. The deviation between numerical simulation results and experimental values shows that the numerical simulation method can predict detonation pressure with 15% uncertainty in the study of detonation rules for small-sized charges.
