To study the detonation performance of 2,4-dinitroanisole (DNAN) based aluminized explosives,the detonating explosive / LiF interface particle velocity and free surface velocity imparted to thin metal plates for aluminized explosives RBOL-2 (DNAN/HMX/Al/additives) and RMOE-2 (DNAN/HMX/NTO/Al/additives) were measured by a laser displacement interferometer system for any reflector (DISAR). The detonation wave parameters were obtained for these two explosives according to the interfacial particle velocity histories. The reaction zone lengths are (1.073±0.111) mm and (1.559±0.094) mm, the CJ pressures are (25.42±0.44) GPa and (20.99±0.15) GPa, and the Von-Neumann pressures are 27.69 GPa and 41.27 GPa for RBOL-2 and RMOE-2, respectively. The velocity histories of the metal plate show that the work capacity of RBOL-2 is better than that of RMOE-2. In addition, under the experimental conditions, the steady detonation status obtained by aluminized explosive is related to the initiation loading conditions and the loading pressure affects the work capacity of aluminized explosives. The greater the loading pressure, the stronger the work capacity. Under high loading pressure (21 GPa), the higher the loading pressure, the more aluminum particles react in the detonation reaction zone, and the stronger the detonation state of the aluminized explosive.
