Study on Pressure Reconstruction Method of Explosion Shock Wave

Shock waves are one of the primary damage parameters an ammunition explosion. Therefore, accurately obtaining shock wave pressure distribution law after explosion is greatly significant for power evaluation and guidance selection in operations course. This study established mapping function between surface reflected free-field pressures, considering altitude effect on pressure. Finite element numerical simulation analysis typical (trinitrotoluene) TNT explosive quality static test were performed, model calculation accuracy was verified by using obtained data. The Validation results show that had 84% could well reflect law. Furthermore, provided a new method scientific data support accurate Additionally, applications engineering testing military.
