In order to precisely validate the parameters of detonation reaction rate model of explosives, a HMX/TATB based explosive PBX-1 was the research subject, and the mushroom test was conducted to study the corner-turning performance of explosives with various detonation propagation diameters. Then the mushroom test was simulated by LS-DYNA program with the three-term ignition and growth model calibrated by Lagrangian gauges measurements. The accuracy in calibrated parameters of the reaction rate model was validated by observing the growth and propagation of detonation waves and by comparing the corner-turning parameters. The comparison between experiments and numerical simulations shows that, the mushroom test can reflect the discrepancy of detonation growths of detonation waves in different directions. Finally, it was proved that the parameter validation of the reaction rate model of explosives is feasible by Mushroom test. © 2021, Editorial Board of Chinese Journal of Energetic Materials.
