Dynamic Response of the Single-Layer Kiewitt-8 Reticulated Dome Subjected to the Airplane Crash

摘要

Aiming to investigate the dynamic response of the single-layer Kiewitt-8 reticulated dome subjected to the airplane crash, events of aircraft impact to the single-layer kiewitt-8 reticulated dome were simulated by using the 3D ANSYS/LS-DYNA. Impact loadings were carried out respectively by the Riera force history method and by modeling a real plane similar to Bombardier Challenger 850. Simulation results indicated that the impact by modeling a real plane directly is more reasonable than the method by Riera force history. Furthermore, a series of different impact events were added to investigate the effect of impact position and the flight attitude of the airplane. It was found that at a certain initial condition, the impact position and the flight attitude can change the damage mode of the dome structure.
