Simulation study on damage efficiency of blasting bomb with blocking wall

Breaking down beachhead obstacle is the key content of the engineering support task of landing operations, and it is of great significance to accurately calculate the obstacle breaking requirements before the obstacle breaking operation begins. In this paper, the damage mechanism of the blasting bomb is analyzed, and a numerical calculation model of the damage efficiency of the breaking bomb is established, and the damage efficiency of concrete target plate and rock target plate with different thicknesses is simulated and evaluated. The simulation results show that the single-shot blasting bomb has a good damage effect on the concrete target plate and rock slab with a thickness of 50 mm, 100 mm and 200 mm, and the obstacle breaking operation can be achieved by firing one or more blasting bomb for the concrete target plate and rock target with a thickness of 500 mm. The research results can provide a method support for the rational use of the blasting bomb and the improvement of combat application efficiency under actual combat conditions.
