Reliability analysis for air-gap detonation transfer interface by numerical simulation

In order to reduce the test samples in the reliability design and assessment, the function process of air-gap detonation transfer interface was simulated by LS-DYNA software. The stress nephograms for the detonation transfer processes of six kinds of design parameters were analyzed. The results show that when the length of air-gap is between 2 and 18 mm, the detonation can be normally transferred which is consistent with the test result of Neyer-D method. The result has referential value for design and analysis of similar products.
