The damage power of the warhead can be judged by making calculation and visualized simulation to the designed warhead and the shooting range parameters.Digital simulation is made to the static blasting process of the warhead in corresponding shooting range by using the theoretical model.Unity3D technology and simulation data are used for creating the mathematical model of the static-blasting field and the 3D scenethus to realize numerical fitting of the simulation data and 3D model animationand enable the users to observe a multi-viewscalable physical process of the static-blasting field in 3D scenes.The analysis of system simulation experiment results show thatthe fitting of system numerical calculation and 3D visual model animation has good effectsand the user interaction experience is satisfyingwhich can provide a basis for making power evaluation to the design and experiment of complex fragment warhead.
