Abstract
In order to study the damage characteristics of typical armored vehicle fuel tank under shock wave load, the shock wave damage process of typical armored vehicle fuel tank is simulated by using finite element software LS-DYNA. In order to obtain the influence law of explosion conditions on the damage of oil tank shock wave, eight simulation conditions were set up, and the influence of charge and explosion distance on the damage effect was analyzed. The results show that when the explosive charge explodes on the side of the fuel tank, the deformation and tearing of the fuel tank occur at the horizontal position corresponding to the explosion center, and the damage degree of the shock wave to the fuel tank varies with the explosive charge and distance. The relationship between the deformation of fuel tank and the peak value of shock wave overpressure is obtained, the structural physical damage criterion of fuel tank is given, and the mapping relationship from physical damage to functional damage of fuel tank is obtained. Based on the damage mechanism of shock wave overpressure to fuel tank, the functional damage probability curve of fuel tank is obtained.
