Method for calculating neck load in pilot ejection process through ground simulation

The invention discloses a method for calculating neck load in a pilot ejection process through ground simulation. The method comprises the following steps: measuring a pure aerodynamic lift value of a head wearing system under a corresponding ejection speed condition; performing inner ballistic performance calculation according to the inner ballistic physical model of the ejection power system to obtain an overload-stroke curve of the pilot seat in an ejection cabin-out stage; obtaining a speed-stroke curve of a head seat in a flow field in the ejection cabin-out stage under the corresponding ejection speed condition through simulation, and finding out the seat stroke under the condition that the airflow speed is maximum according to the speed-stroke curve; finding a seat overload value when the seat travel is s according to the overload-travel curve; adding the actually measured weight of the head wearing system to the head weight of the corresponding pilot to obtain the weight of the head system; and obtain
