摘要

Due to the high diving speed and large aircraft mass, the ship deck will suffer a very huge impact load during the carrier based aircraft landing. Therefore, the identification of impact load is beneficial to evaluate the safety of deck structure and can provide accurate load input for the optimization and specification formulation of new generation of ship deck design, which is of great engineering importance. However, the current studies of aircraft landing impact were mostly drop tests which conducted in the laboratory, lacking research on deck impact. In order to study the impact response of the aircraft to deck, finite element method was applied to model and simulate the aircraft tire impact on ship deck. The tire was composed of tread, sidewall, belt, bead, carcass and rim. With rubber as the main material, the sidewall and tread were adopted with Mooney-Rivilin constitutive model. By comparing the simulation results with the test results of publication, the reliability of the model was confirmed. This study obtained the impact response applicable to general ship decks by modeling and simulating the impact of aircraft tires on ship decks, which was of great help in identifying landing impact load.
