To analyze detonation wave of the JO-9159 shaped charge explosive, the equation of state of JWL , and the combination equation of JWL and γ were used respectively to characterize detonation product sate of the JO-9159 shaped charge explosive, and detonation wave were obtained based on the different equation of state. Variation rules between detonation wave of specific location and time was got by a high-speed scanning camera, results comparison between simulation and test shows that detonation wave calculated by the combination equation of JWL and γ was closer to the experimental results, which proves the combination equation is more accurately to describe detonation product state of the JO-9159 shaped charge explosive. The research results offer references to analyzing detonation wave of shaped charge and designing of shaped charge warhead.
