The invention discloses an aircraft wheel complete ejection load spectrum dynamic simulation system and method, and the system comprises a movable towing bracket, an aircraft wheel, and a flywheel which is used for providing the speed for the aircraft wheel. The loading module is used for providing a load for an aircraft wheel; the state observation module is used for pre-estimating and measuring the load of the aircraft wheel; the FFC + FBC composite control module is used for controlling the loading module to simulate the load change of the aircraft wheel when the aircraft wheel is completely catapulted; the system can accurately measure the load borne by the aircraft wheels and perform high-sensitivity adjustment, has a rapid following property, can reduce the static difference of the load and improve the response effect, and further can completely and truly reflect the high loading rate and the loading rate sudden change characteristic in the catapult-assisted take-off process of the aircraft, so that the aircraft catapult-assisted take-off performance of the aircraft is improved, and the aircraft catapult-assisted take-off performance of the aircraft is improved. Therefore, the tire characteristics and the service life of the aircraft in the catapult-assisted take-off process can be tested.
