摘要	Generally, the time-dependent impact force of a commercial aircraft against a rigid wall can be calculated based on the Riera's model, which consists of the static crushing force and the dynamic force. The reduction coefficient a is generally considered to be less than a unity in the modified Riera's function, while the influence of the impact velocity on the reduction coefficient is not investigated before. Moreover, the static crushing force is hard to be determined in practice. Thus an engineering model was proposed in the present study, and the total force was only described by the dynamic force and another velocity-dependent coefficient y. Based on a well-defined finite element model for the commercial aircraft Boeing B737-800, the entire impact process of the aircraft impinging on a rigid wall was reproduced by the commercial software LS-DYNA, and four different impact velocities (150, 200, 250, 300 m/s) were considered. Based on the simulation results, the influences of impact velocity on the two coefficients (alpha and gamma) were investigated and discussed by matching the aircraft impact force/impulse with the reaction force/impulse of the rigid wall. Finally, two formulas for the effects of impact velocity on the two coefficients were proposed, which is helpful for the engineers in designing and assessing the protecting shell of the nuclear power plant.
