A kind of rope-suspended astronaut microgravity environment simulation training device and training method

Abstract

The invention provides a rope suspension type astronaut microgravity environment simulation training device and training method. The device comprises a steel wire rope, a simulation load, a cross bar,a handle, a suspension mechanism, a swing mechanism, a force sensor and an angle sensor. The steel wire rope bears all gravity of the training device; the small-diameter steel wire rope is used, thelength of the steel wire rope is increased, and the torsion angle of the training device is controlled to be smaller than 20 degrees, so that the torsional moment of the steel wire rope can be ignoredrelative to the inertia moment of the simulation training device; therefore, the rotating motion effect of the training device around the axis perpendicular to the horizontal plane is equal to the motion effect in the space, an astronaut can change the motion state of the training device by pushing and pulling the handle, and the training task of carrying objects in the microgravity environment can be simulated on the ground.

Description

technical field [0001] The invention relates to a rope-suspended microgravity environment simulation training device and training method for astronauts. The invention belongs to the new technical field emerging with the development of aerospace technology: ground microgravity simulation training for astronauts. Compared with digital simulation and theoretical evaluation, the experimental data obtained through microgravity simulation is more authentic and reliable, and has irreplaceable advantages. Different from other physical effects, gravity is a component of gravitation. It does not require contact and cannot be eliminated or isolated by existing scientific methods. A simulation system is established on the ground to simulate the microgravity environment in space, which is generally realized by mechanical devices. Background technique [0002] From the earth to space, from a gravity environment to a weightless environment, although the astronauts cannot feel the gravity o...

AI Technical Summary

Problems solved by technology

[0009] The air flotation method and the magnetic levitation method use compressed air or magnetic force to separate the object from the contact surface, so that the object is not affected by friction, and the air pressure or magnetic force is reasonably controlled to offset the gravity of the object. This microgravity simulation method is effective, but the cost is high

Water flotation is to let objects and astronauts submerge in the water, and use the buoyancy of water to offset gravity. Water flotation cannot eliminate the influence of fluid resistance on the simulated environment, and astronauts need to carry oxygen supply devices, which makes them inconvenient to move.
