Numerical Investigation of Static Blast Pressure Fields of TKX‐50‐Based Explosive Charge

TKX‐50‐based explosives, owing to their high detonation performance and low sensitivity, are considered promising candidates for future warhead main charges. Existing studies have primarily focused on synthesis optimization, composite material design, thermal decomposition mechanisms, and basic detonation parameters, whereas investigations into the static blast pressure field of TKX‐50‐based explosives remain limited. In this work, a numerical simulation model of the static blast shock wave pressure field of TKX‐50‐based explosives was established using LS‐DYNA. The simulated overpressure results show good agreement with experimental data, with deviations within 6%, demonstrating the reliability of the proposed model. On this basis, the effects of key operating parameters—including scaled distance, burst height, length‐to‐diameter ratio, and initiation mode—on the shock wave pressure field of TKX‐50‐based explosives were systematically investigated. Furthermore, LS‐OPT was coupled with LS‐DYNA to conduct optimization analysis, through which a numerical prediction of the optimal blast height was determined within a selected range of parameters.
