Abstract

The impact processes of an Airbus A320 airplane upon a rigid target under different impact velocities and different impact angles are simulated by using the general explicit dynamic analysis program LS-DYNA. Through comparing the numerical simulation results of the impact loads with the calculated results of the modified Riera impact load equation, the correction coefficient α in the modified Riera impact load equation under different impact velocities are determined. It is showed that the correction coefficient α is not a constant, moreover, there is a linear relationship between α and the square of the impact velocity V₀². The impact loads calculated with the modified Riera impact load equation are in good agreement with the numerical simulation results, which verifies the rationality of the modified Riera model.
