Abstract:In this paper, a refined finite element model of Boeing767-200ER is developed, considering actual mass distribution, structural stiffness, and material properties. The rigid wall aircraft impact simulations are performed by LS-DYNA program, to obtain the impact and impulse time histories, and analyze the effect of different initial velocities and airframes. Then the analysis of the aircraft impact on the concrete containment building shows that, the impact force and impulse by the aircraft are influenced according to the sectional shape and relative stiffness of the target. The analyses are necessary for further research on aircraft impact threats to NPP.
