Dynamic Simulation And Analysis For Arresting Process Of Carried-based Aircraft

Carrier-based aircraft landing environment is very complex,it needs the ship's arrest system to achieve the ship blocking process.However,due to factors such as aircraft carrier's movement,bouncing on the hook blocking deck and vibration of the cable compressors,there is a possibility of blocking failure,resulting in landing on board unsuccessfully and causing major safety accidents.Based on the research of a carrier-based aircraft,a six-DOF full-body dynamics model and a dynamic analysis model of landing gear,blocking hook and cable were established.By blocking the hook bounce test and landing gear dropping experimental data,kinetic model was verified and corrected.Based on the above dynamics model,the influence of pitch angle,roll angle and sinking velocity on the rebound of barricaded hooks is analyzed.The influence of pitch angle and roll angle on the movement of barricaded barrels is analyzed.The effects of parameters such as subsidence velocity,heading velocity,pitch angle,roll angle and eccentricity on the success rate of barricade hooking were studied.The batch calculation of multivariable combination was carried out to analyze the general influence law of each variable on the success rate of hanging bar.Based on the batch database,the agent model of barricade hook barber is established,which mainly analyzes the influence of the mean and variance of the distance among the barrier hook and the barrier on the success rate of barrister,And giving suggestions for improving the success rate of landing tackles.
