For the dispersing interior ballistic process of the steel bag dispersal mechanism of the cluster warhead,a novel model is proposed and the simulation is carried out. The system structure and the work principle of the steel bag dispersal mechanism are analyzed. The steel bag movement model, and the volume and the valid thrust area change models are built according to the characteristic of the steel bag expanding and working process. The curves of ballistic performances are simulated by the compiled process. The computational results prove the model's feasibility. The research here can give methods for the constructional design and the charge design of the steel bag dispersal mechanism.
