Abstract
The invention is applied to the field of aerospace and aims to simulate a weightless environment for astronauts and people who want to experience a microgravity environment and carry out a simulation test of work in a space capsule. Based on the principle of an electromagnetic crane, the invention counteracts part of gravity of a human body by attraction force generated by the electromagnet (7) to the magnetic clothes (3), and dynamically adjusts the stress condition of the human body in real time under the tuning of the control system (8) through various structures, so that the human body has stronger weightlessness participation sense and the space environment is simulated.
Description
Technical Field
The invention is applied to the field of aerospace, provides a device for enabling astronauts to experience experimental operation under microgravity, and is used for people to experience the feeling of the microgravity.
Background
At present, weightlessness training of astronauts is finished by using weightless airplanes. The weightless airplane can finish parabolic flight, and microgravity time of 15-40 seconds is formed. The astronaut can feel, experience and be familiar with the weightlessness environment, can do various tests in the weightlessness time, such as eating, drinking, wearing and taking off clothes, closing eyes and opening eyes directional movement, even can move a cabin body into the cabin, can also carry out the test that the astronaut climbs out of the cabin body in the weightlessness time, and trains the space to move out of the cabin.
The small weightless aircraft in the United states are the weightless aircraft modified from T-33 and F-104 aircraft. The large weightless airplane is KC-135 and PC-9, and the Soviet Union/Russia is modified by Ier-76, and the microgravity time of the airplane is about 30 s. The French nation has 'fast sailing' and A300 weightless airplanes, and A300 is the largest weightless airplane in the world at present. There are also large or medium sized weightless aircraft in japan. China changed Jian-5 into a small weightlessness airplane.
The floating feeling generated by the neutral buoyancy water tank can be used on the ground to simulate and train the astronauts to work and maintain during weightlessness. The principle of simulating weightlessness of the neutral buoyancy water tank is that when a human body is immersed in water, the gravity and the buoyancy of the human body are equal by increasing or decreasing the balance weight and the floater, namely the neutral buoyancy, so that the feeling and the effect of simulating weightlessness are obtained; it does not eliminate the effect of gravity on the human body and its tissues, and therefore, it is different from a real weightless environment. At present, the method is mainly used for training astronauts for out-of-cabin activities. Generally, the ratio of 1: the spacecraft of 1 is put into a water tank, and a spacecraft wears a reformed extravehicular space suit to simulate an out-of-cabin activity program and train skills.
The invention is based on the principle of an electromagnetic crane, and simulates a space environment through the cooperative work of a control system (8) and each sensor, is oriented to astronauts and common people experiencing microgravity effects, is used for experimental operations (such as plant cultivation, measurement data and the like) and daily activities and the like under the microgravity experience, counteracts the gravity of a human body by the electromagnetic attraction of an electromagnet (7) to a magnetic coat (3), and keeps the dynamic balance of the personnel in the device through the cooperative control of the control system (8) and each part of sensors, but cannot simulate the weightlessness effect of an outer space real force field to human body tissues due to the fact that an external force field acts on the human body, so that the invention provides the feeling similar to the microgravity in the space and is different from the real space weightlessness environment.
