The invention discloses a steer-by-wire hand feeling simulation device comprising a steering shaft which is fixedly connected with a steering shaft worm wheel; an output shaft of the motor is connected with the worm; the worm and gear pair is formed by meshing a steering shaft worm gear and a worm; the torsion piece is coaxial with the steering shaft, and the first end of the torsion piece is fixedly connected to the end face of the steering shaft worm gear and used for restraining the steering angle range of the tubular column and enabling the steering wheel to automatically return to the neutral position through torsion; when no external force exists, the torsion piece is in a natural state to enable the hand disc to be in a zero position; the corner position sensor determines a mounting position and a use type according to the type of the motor; wherein the center line of the steering shaft, the motor and the second end of the torsion part keep relative coordinates unchanged in a specified coordinate. According to the steering-by-wire hand feeling simulation device, on the premise that a steering intermediate shaft is not configured and no external assistance exists, the steering angle stroke of the steering-by-wire hand feeling simulation device can be restrained, the steering angle certainty is achieved, and the torque characteristic of a mechanical steering system can be simulated.
