REDUCED GRAVITY SIMULATION METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC A61B5/00 B64G7/00 G09B23/28 

FIELD: medicine.

SUBSTANCE: group of inventions relates to a method and device for modeling reduced gravity of a given level. The device is a vertical metal frame with a platform. The platform is made with the ability to move under the control of the control system. The control system contains position sensors, an installation controller with an installed motion control program, a stepper motor and a stepper motor driver. Drivers provide cyclic lifting and lowering of the platform. Two profile rail guides are attached to the vertical metal frame. The platform is made with the possibility of moving along profile rail guides using two linear movement modules due to a stepper motor. The platform is connected to the stepper motor shaft by means of two pairs of cables. The stepper motor is fixed on the transverse beam of the supporting frame, 4 cables are attached to its shaft. Two cables are directed upwards, the other two are directed downwards. Both pairs of cables thrown at the top and bottom of the frame through roller pulleys with a U-shaped groove, are attached to the platform with tension in such a way that the rotation of the shaft leads to the simultaneous tension of the cables pulling in one direction and the weakening of the cables oriented to movement in the other direction, to cause the platform to move up or down. The platform is lifted to a height at a constant speed. The descent of the platform is carried out with a programmed acceleration. Acceleration develops on the upper 2/3 of the way down, then the phase of a uniform decrease in speed to zero at the bottom point begins. Gravity simulation is achieved by vertical descent from a given platform height with controlled acceleration set by the operator. On the last segment of the vertical trajectory, the platform is smoothly braked until it stops completely.

EFFECT: simulation of the effects of reduced gravity of a given level for a long time is provided in the absence of a mechanical effect on the subjects with the possibility of current control of the effects of the influence of reduced gravity on the state of the physiological systems of the body.
