摘要：
The finite element code LS-DYNA was used to numerically simulate the process of shaped charge jet vertically penetrating a diesel oil filled airtight structure. The reliability of the simulation method was validated by X-ray photographies and residual depth penetration experiments of a jet penetrating a 30 mm lumen diameter, 30 mm lumen height and 5 mm wall thickness diesel oil filled airtight structure at 0° dip angle. The penetration resistance of diesel oil filled airtight structures with different dimensions was studied. The effects of dimensions of airtight container on the stability of jet and the residual penetration ability when the jet penetrates the structure were analyzed. The results show that the radial imploding of diesel oil will seriously disturb the stability of jet. The vessel lumen diameter and height have influence on the length and position of velocity interval of the disturbed jet. The vessel wall thickness affects the intensity of the radial imploding of diesel oil. © 2016, Editorial Office of Journal of Vibration and Shock. All right reserved.
