Abstract:
In order to study the crash resistance of the civil aircraft structure in different crash environments， two environmental models of soft soil and water are established to analyze the dynamic response of the fuselage section subjected to the vertical at the impact velocity of 7 m/s. Simulation results show that the soft crash environment can have a certain cushioning effect on the structure crash， but it will prolong the crash time and change the energy absorption mode. This work suggests that soft environment may not be suitable for forced landing.
