Simulation Analysis and Model Verification of Airborne Vehicle Landing Buffer
Based on the impact load of airborne vehicle during landing buffering,the coupling finite element model of airborne vehicle-buffer bag was established and the landing buffering process simulation was carried out.The ground drop simulation test under typical vertical landing conditions was conducted,and the simulation data was compared with the test data to verify the accuracy of the simulation model.The simulation analysis of the landing buffering process under vertical landing condition with horizontal velocity was carried out,and the landing buffering responses such as vehicle impact load,rebound speed and airbag internal pressure were checked.The simulation results show that for a certain airborne vehicle,the current design scheme of airborne vehicle-buffer airbag can meet the impact load requirements under various working conditions.This method can satisfy the optimization of airborne vehicle scheme and the prediction of landing buffer performance.
