Numerical Simulation of Anti-tank Rejector Blast Damage Calculations

In order to study the damage law of anti-tank horse repellent by charge explosion, ANSYS/LS-DYNA software was used to carry out numerical simulation calculation of anti-tank horse repulsion explosion damage, and the kinetic response process of anti-tank horse repulsion under two doses of 500kg and 1000kg and different burst distances was analyzed, and the damage mode and critical detonation distance of anti-tank horse repulsion were obtained. The results show that the anti-tank horses near the explosion source mainly have serious bending and deformation, tumbling and being swept away. The anti-tank horse deformation damage at a distance from the explosion source is less obvious, and it is mainly manifested as overall tumbling or translation. For the anti-tank horse rejection array, when the burst distance is small, the horse rejection is affected by the shock wave and scatters backwards, and it is distributed in an arc along the shock wave front, and the distance between the horse rejection is significantly increased. When the burst distance is large, the repellent horse rolls backwards for a shorter stroke and forms a buildup. Taking the maximum distance between the horses as the damage standard, the critical bursting distance of the anti-tank anti-tank anti-horse formation damage under 500kg of charge is 11 times the charge radius, and the critical bursting distance of 1000kg of medicine is 10 times the charging radius.
