摘要
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.
