Abstract

The finite element code ANSYS/LS-DYNA was used to numerically simulate the process of dynamic response of three kinds of explosion-proof pots under explosive loading of 1.2 kg TNT. Antidetonation property of explosion-proof pots made of different sandwich structure with no-sandwich, polyurea elastomer and rubber was studied. The effects of different sandwich structure for global deformation of explosion-proof pot and energy absorption characteristic of polyurea elastomer sandwich and rubber sandwich were analyzed. The reliability of the simulation results was validated by deformation experiment of explosion-proof pots made of polyurea elastomer sandwich under explosive loading. The results demonstrated that explosion-proof pot made of sandwich structure with polyurea elastomer is superior to the ones without sandwich and made of rubber sandwich under the same explosive loading, either in deformation or in energy absorption. Attenuating range of shock wave propagation in polyurea elastomer is the largest.
