The invention discloses a simulation method and device for a crossed double-rotor unmanned helicopter. The method comprises the steps: determining the induced speed of a rotor wing according to the rolling operation amount and the pitching operation amount, determining the flapping angle of the rotor wing, and then determining the lifting force, the lateral force, the backward force, the rolling torque, the rotor wing shaft torque and the pitching torque of a fuselage according to the induced speed and the flapping angle of the rotor wing; determining a resultant external force and a resultantexternal moment of the fuselage on the X axis, the Y axis and the Z axis of the fuselage coordinate system according to the lift force, the lateral force, the backward force, the rolling moment, therotor shaft torque and the pitching moment of the fuselage, and determining flight parameters of the crossed double-rotor unmanned helicopter according to the resultant external force and the resultant external moment of the fuselage on the X axis, the Y axis and the Z axis of the fuselage coordinate system. According to the scheme disclosed by the invention, the flight parameters of the crossed double-rotor unmanned helicopter can be accurately simulated.
