Active and passive hybrid drive self-adaptive gravity unloading astronaut ground training system

Abstract

The invention discloses an active and passive hybrid drive self-adaptive gravity unloading astronaut ground training system, which performs modular grading aiming at continuous quality characteristics of a human body, adopts a passive hybrid tree-shaped bifurcated driving mechanism, and combines a multi-point distributed gravity unloading strategy, so that additional joint force during astronaut training is effectively reduced, and the training quality of astronauts is improved. Therefore, the trueness and immersion of the micro-low gravity simulation training of the astronaut are improved. A truss vehicle two-degree-of-freedom motion platform is adopted to realize large-range space two-degree-of-freedom translation of the whole human body; and a self-adaptive gravity unloading system is combined to realize the large-range movement of the whole human body in the vertical direction and the small-range six-degree-of-freedom movement of the trunk, the four limbs and the head of the human body. Decoupling design is carried out for overall large-range movement and local small-range movement in the human body floating base state, and the training requirements of astronauts for multiple postures and multiple movement modes are met.

Description

technical field [0001] The invention belongs to the technical fields of aerospace micro-low gravity simulation, sports training, fitness and entertainment, mechanical engineering, etc., and specifically relates to an active-passive hybrid drive self-adaptive gravity unloading astronaut ground training system. Background technique [0002] my country's manned spaceflight project is developing rapidly, and space station construction, on-orbit construction, and on-orbit maintenance require more astronauts to enter space; internationally, NASA announced a manned landing plan on Mars, and SpaceX launched a plan for private transportation and interstellar travel. The activities gradually expanded to space. The low-gravity environment of space will cause various negative effects on the human body, including poor balance, changes in limb movement patterns, and muscle atrophy, which seriously affect the safety, health, and work efficiency of astronauts. In order to ensure the health ...

AI Technical Summary

Problems solved by technology

However, most of the existing suspension systems adopt single-cable or few-cable schemes, and lack the distributed unloading analysis and design of multiple suspension points. Low-gravity immersion is reduced; at the same time, there are many training equipment for a single motion mode, such as upright walking, jumping, etc., and there is a lack of research on continuous adaptive gravity unloading training equipment for astronauts' autonomous multi-sport modes
