Abstract
Polyurea coating has excellent anti-explosion performance. In order to solve the problem of sympathetic detonation of a fuze, a polyuria-coated packaging barrel is designed. ANSYS software is used to simulate the sympathetic detonation test to verify the anti-explosion performance of the packaging barrel. The shock wave and explosion products produced from explosion are obviously hindered. The packaging barrel and the fuze body are damaged but the booster of the fuze is not detonated. The maximum pressure of selected elements in booster is 13.0 GPa, which is less than the initiation pressure of TATB in the booster. The acceptor fuze is not sympathetically detonated. A sympathetic detonation test is carried out and the results are consistent with the simulation.
