The Numerical Simulation Experiment of Exploded in the Flat Box Sealed Structure

Abstract:

Basis on the theory of mechanics of explosion, according to nonlinear finite element method shows that dynamic analysis software ANSYS/ls-dyna , the explosion wave propagation in the flat box sealed structure and the distribution of overpressure on the wall is studied under the action of explosion. Combining the reality of ^[Guo Zhikun experiment and basic data , ANSYS/ls-dyna is used to establish a standard size 4 studio flat box experimental model, within the model corresponding to the positioning of the drug to 220 units of TNT. Through ANSYS/ls-dyna visualization process study the transmission mechanism of shock wave in a flat trunk, acquisition of some points on the wall of the overpressure peak data caused by explosion, combined with experiments of the proceeds of the actual data values were analyzed.
