The invention discloses a device for passengers to rotate in a space
capsule. The device comprises a supporting part on the space
capsule, a supporting shaft, a
crankshaft or a
crank fixedly or movably connected with the supporting shaft, an elastic device and a
loader capable of carrying people to rotate, wherein one end of the elastic device is movably connected with the
crank pin or the
crank pin, and the other connecting end of the elastic device is connected with the supporting part or other fixing devices; the
loader is formed by connecting a suspension pull part and a manned part; the suspension pull part is directly or indirectly fixedly connected with the
crankshaft or the crank, and swinging or rotating of the suspension pull part enables the linked
crankshaft pin or crank pin to be subjected to correspondingly changed force of the elastic device; the manned part bears the body of a passenger or provides
centripetal force required by
circular motion of the passenger; the operating method of the device comprises the steps that the moving direction of the
mass center of a passenger relative to the suspension pull part is preferably consistent with the direction of torque which is borne by the suspension pull part and transmitted by a crankshaft or a crank through an elastic device, or the movement in the direction is carried out when the torque borne by the suspension pull part is large or maximum; the swing amplitude or the rotation speed of the
loader can be increased through repeated operation, and the effects of feeling the
artificial gravity and building the body are achieved.
