In this paper, the damage effect of shock wave on the closed cubic structure is studied. Based on the free-field shock wave theory, the propagation law and characteristics of the explosion shock wave in the closed cube are analyzed, and the conduction formula is derived. By adopting method of the theoretical calculation of the feature points of the cube model and the numerical simulation of LS-DYNA finite element analysis software, the theoretical calculation values and numerical simulation values of the first shock wave over-pressure of different measuring points were compared. The results show that the simulation values of the three characteristic points in the closed cube are consistent with the theoretical calculation values, which can provide a theoretical reference for the selection of the sensor and the arrangement of the measuring points in the actual measurement.
