An analysis method of strain data in time domain and frequency domain is researched for the strain measurement in anti-shock test on warship under no-contact explosion. Several explosion tests under different conditions are implemented on the scaled model. Based on the analysis of strain data in time domain and frequency domain, it is revealed that there are different natural vibration frequencies in the vertical and longitudinal directions, and there is a certain relationship between the strain curves of time domain and frequency domain. ©, 2014, China Ordnance Society.

The semi-sphere shaped charge is featured by thick and short jet with large perforation diameter, larger mass jets and so on. The damage effect of a shaped charge warhead on submarine cabin is simulated using smoothed particle hydrodynamics (SPH) method. The damage process of the warhead, the jet velocity and structural damage modes are analyzed to provide a reference for the new design of shaped charge warhead. ©, 2014, China Ordnance Society.
