Fine evaluation method and device for seaborne forced landing passenger injury of hovercar

The invention discloses an aerocar seaborne forced landing passenger injury refined evaluation method and device, and the method comprises the steps: obtaining and assembling an aerocar body model, a constraint model and a simple passenger model, constructing a forced landing vehicle model, executing forced landing numerical simulation on a forced landing water area model, and generating simple passenger injury evaluation data step by step; when the simple passenger injury evaluation data at any time step exceeds the passenger part injury range, transmitting unit information at the current time step so as to automatically update a simple passenger model in the forced landing vehicle model by adopting a refined part model; and continuously executing the forced landing numerical simulation from the current time step until the forced landing numerical simulation is finished, and constructing a passenger injury refined evaluation result. Therefore, the data calculation amount in the seaborne forced landing simula
