1. A simulator joystick force calibration method, comprising:
step S1: powering on a simulator, activating a hydraulic system, and performing pressurization on elevator hydraulic systems A and B;
step S2: moving a joystick forward and backward, placing the simulator in a neutral position, and ensuring that an angle between an axis of the joystick and an axis of a vertical position falls within a preset angle range;
step S3: disposing a simulator joystick force measurement device on the joystick of the simulator; disposing dynamometers at multiple positions on a force measurement surface of the simulator joystick force measurement device; moving the joystick by the dynamometers, and maintaining the joystick at a preset elevator position; recording joystick forces at all the positions via sensors connected in the joystick; and ensuring that forces applied to move the joystick by the dynamometers remain within a preset range;
step S4: determining whether the joystick force at each position matches a joystick force at a corresponding position of an actual aircraft; if not, proceeding to step S5; and if yes, proceeding to step S6;
step S5: performing, for an elevator position corresponding to a joystick force not matching a joystick force at the corresponding position of the actual aircraft, a joystick force calibration based on a position parameter; and returning to the step S4 after the joystick force calibration;
step S6: obtaining actual flight force feedback from a standard aircraft instructor; determining whether the joystick force is normal; if yes, proceeding to step S7; and if not, returning to the step S5; and
step S7: moving, based on different positions of the force measurement surface, the joystick to different angles by the dynamometers; recording joystick force values displayed on the dynamometers at each angle, and comparing the joystick force values with corresponding verified normal simulator data; filtering out abnormal data; calculating an average of remaining multi-angle and multi-position joystick force values as a standard simulator joystick force parameter; and establishing an industry standard;
wherein the simulator joystick force measurement device comprises a joystick connection device and the force measurement surface;
two ends of the joystick connection device are disposed on the joystick; the force measurement surface is disposed between the two ends of the joystick connection device; a plane where the force measurement surface is located and a plane where the joystick connection device is located are arranged at an inclination; and the dynamometers are disposed on the force measurement surface and are configured to measure the joystick forces;
the joystick connection device comprises two first cover plates and a second cover plate;
the two first cover plates are symmetrically fixed along a center of the force measurement surface at two sides of the force measurement surface; and the two first cover plates are detachably fixed to the second cover plate;
a gap is provided between each of the two first cover plates and the second cover plate; and the joystick connection device is sleeved onto the joystick through the gap; and
that the two first cover plates are detachably fixed to the second cover plate is structured as follows:
threaded holes are provided in each of the two first cover plates; and bolts are connected to the threaded holes respectively via threads and disposed on the second cover plate.
