The body senses gravity by the otolith apparatus located in the inner ear labyrinth, which consists of calcium carbonate crystals (otolith) attached to the hair cell gel matrix (the sac spot). Otoliths move and hair cells deform when the body tilts or accelerates, and otoliths cannot distinguish between tilting and linear acceleration stimuli. Static horizontal tilt of 15 °, 25 °, 30 ° and 45 ° with linear acceleration produced 0.27g, 0.46g, 0.58g and 1g stimulation, respectively, at the balloon plaque plane.

The relationship among the three is as follows: tan θ ═ F/G; in addition, F is m.r.omega2Where m is the trainee's weight, r is the distance of the seat from the center of rotation (radius of rotation), and ω is the angular velocity of rotation; g ═m · g, g is the gravitational acceleration of the earth's surface.
When the trainee rotates at a constant speed of 33 degrees/s under the condition of 50cm eccentricity facing to the rotating direction, the perception that the human body is horizontally inclined by 9.5 degrees can be generated, and the stimulation of g/6 lunar gravity is generated on the saccule speckle plane by the linear acceleration similarly.

The space orientation adaptability training device for simulating the celestial body gravity provided by the embodiment preferentially trains against the lunar body gravity, and relates to three aspects of a g/6 vestibular stimulation generation mode, a lunar surface activity scene and orientation tasks with different difficulties. The elastic handle is adjusted through the eccentric adjusting device 12 according to the gravity condition to be simulated, so that the distance between the seat and the rotation center is adjusted, and the human trainee can appropriately bear the stimulated eccentric rotation speed. Namely, the eccentric adjusting device 12 adopts an adjusting control elastic handle and a graduated scale positioned on the eccentric device, and is used for determining the distance between the adjusting seat and the rotation center (the maximum eccentric distance is 50cm), and carrying out centrifugal stimulation according to a specified speed profile.
The seat can rotate according to the set speed profile curve, including the trapezoidal speed curve, the sine harmonic curve and the like under the eccentric state, and the maximum speed can reach 450 degrees/s. The seat is capable of eccentric clockwise and counterclockwise rotation, and the trainee can rotate toward, away from, or outward.
In training, the seat of the swivel chair 11 is first pulled out in parallel to an eccentric distance (50 cm in this embodiment). According to the gravity level to be simulated, for example, the gravity level of the moon is g/6, the rotation angular speed of the chair is set to be 33 degrees/s, a human body can feel g/6 motion stimulation and 9.5 degrees of inclination perception, meanwhile, a trainee wears a visual helmet and generates a lunar activity scene through a visual generator, and the trainee performs operation and training according to the task set by the scene to achieve the effect of simulating space orientation training under the gravity condition of the moon.
In training for simulating the gravity condition of the moon, the images and commands generated by the virtual scene and task command generating system 31 include images and sounds of the lunar hills, the lunar base, the lunar vehicle, the scene in and out of the lunar vehicle cabin, and the operation commands. The content generated by the virtual scene and task command generating system 31 is transmitted to the light wireless virtual reality viewing helmet 21 and the headset 22 by wireless transmission, and the trainee performs a training task by wearing the light wireless virtual reality viewing helmet 21 and the headset 22 in combination with the operation handle 23.

The operating handle 23 is made of a hard material in this embodiment. The operating handle 23 is used for performing operation interactive control on lunar virtual articles in the training process, and because the physical movement of a trainee is limited, and the trainee cannot perform actual walking, stooping and other actions in the training process, special design needs to be performed on an operation interactive mode, and the direction keys of the operating handle 23 are used for controlling the searching, walking, lunar vehicle control, direction change and other movements; for actions such as selecting and picking up an operation target, a virtual picking-up device is established on the operation handle 23, the picking-up device can emit visible rays in a virtual scene, the selection of a virtual object is realized by collision detection of the visible rays and the virtual object, and the picking-up and operation of the object are realized by operation keys on the handle; for the actions of carrying, throwing, displaying national flags and the like, the virtual object can be attached to the operating handle 23, and the operation on the virtual object is realized through the setting and the release of the follow-up relation.
In this embodiment, the operation interactive control of the lunar virtual object includes searching, carrying, throwing, controlling the lunar vehicle, changing the advancing direction, completing tasks of displaying national flags and the like, and interactive control contents can be freely developed and designed according to training requirements.

5) The swivel chair 11 is started, the swivel chair 11 is at 10 DEG/s2Accelerating to 33 degrees/s to reach the platform speed for uniform rotation. When the revolving chair 11 reaches the platform period speed of 20s, the training task is started (after the acceleration period is finished, the feeling of the human body to the acceleration can still last about 20s, so that the training task is started after the revolving chair 11 reaches the platform period of 20s, which is beneficial to avoiding the adverse effect of the acceleration stimulation on the training).
6) After the training is finished, the speed of the swivel chair 11 is reduced by 10 degrees/s (the setting range is 0-450 degrees/s) until the swivel chair 11 stops rotating.
