In order to build the computing model of cylindrical warhead fragment dispersing parameters, considering the influence of the ratio of length to diameter and the type of fragment, the revised Gurney equation was used to construct the axial distribution model of warhead fragment initial velocity. The fragment deflection model with high precision was modified by revised Shapiro formula. The calculated values of the model was identical with the experimental results and had better integrated performace than existing models.
