Exoskeleton type man-machine back frame system for astronaut micro-low gravity simulation

Abstract

The invention provides an exoskeleton type man-machine back frame system for astronaut micro-low gravity simulation, which comprises a three-dimensional rotating mechanism, an exoskeleton bracket mechanism and a gravitational torque compensation mechanism, and is characterized in that the exoskeleton bracket mechanism is rotationally connected with the three-dimensional rotating mechanism; the gravitational torque compensation mechanism is arranged on the three-dimensional rotating mechanism and connected with the exoskeleton support mechanism. According to the exoskeleton type man-machine back frame system for astronaut micro-low gravity simulation, the gravitational torque compensation mechanism is arranged on the three-dimensional rotating mechanism to connect the three-dimensional rotating mechanism with the exoskeleton support mechanism and is used for compensating gravitational torque when the exoskeleton support mechanism rotates along with three axes of the astronaut; therefore, the weightlessness of the astronaut in the directions of three rotational degrees of freedom is simulated, so that the somatosensory of the astronaut in a micro-low gravity environment is truly simulated.

Description

technical field [0001] The invention relates to the technical field of microgravity simulation, in particular to an exoskeleton-type man-machine back frame system for astronaut micro-low gravity simulation. Background technique [0002] There are complex environments different from the earth's surface in space and on the surface of alien planets, such as high-radiation, high-vacuum, and low-gravity environments. Among them, the micro-low gravity environment has a great impact on spacecraft and astronauts. During the execution of space missions, astronauts will experience a completely different body sensation from that under ground gravity, which greatly increases the time required for space mission execution and reduces the Increased risk of mission failure. [0003] In order for astronauts to adapt to the low-gravity environment in space in advance, it is necessary to simulate the low-gravity environment in space through experimental equipment on the ground for astronaut t...

Problems solved by technology

However, the existing suspension method has certain limitations in simulating the micro-low gravity environment. Most of them can only realize the micro-low gravity simulation of three-dimensional translation, and cannot realize the three-axis rotation of astronauts, and the simulation level is limited; while a small part can realize the simulation of astronauts Three-axis rotation suspension method technology, such as the simulation system developed by NASA in the United States, which adds a man-machine back frame that can realize three-axis rotation of astronauts on the basis of the suspension type. Rotary joints cannot simulate the weightlessness of astronauts in the direction of three rotational degrees of freedom, that is to say, the gravitational moment generated at the joints of the astronauts during three-axis rotation is not compensated, and the body feeling is not accurate
