The Body Weight Gain Technology Reserch Of Weightlessness Environment

The space technology rapid development, in order to overcome the harm to human body caused by weightlessness outer space environment, need to resist gravity training of astronauts. Currently antiweightless environment exercise program at home and abroad, even at maximum power output, the astronauts still can not achieve the requirements of exercise intensity, and many training methods need space, which is difficult to achieve. Based on the above situation, this paper presents a weight gain of unpowered passive technology that does not require an external power supply and control systems, using a spring elastic potential energy increase of gravitational potential energy of the body, which has a simple structure, safe and good stability and other characteristics. This weight gain technique can be used for anti gravity training astronauts in space environment, can achieve better protective effect against weightlessness, through parameter Settings, also can shorten the time of the astronauts against weightlessness exercise, therefore, has the very high theoretical research value and good application prospect.This article, focusing on the human body weight gain of weightlessness environment technology method, has carried on the simulation analysis and experimental research. In this paper, the main research contents include:1) research and design of gravity increase technology overall plan;2) dynamic simulation and analysis of resistance training device;3) adaptive weight method;4) resistance training device mechanical structure design and finite element analysis;5) prototype design and experimental analysis of resistance training device.This paper is expected to reach these goals, analyze the technical characteristics of existing gravity increase technology, proposed the new method of using gravitational potential energy spring elastic potential energy increase system, complete weight technology scheme design, dynamics modeling and simulation as well as the dynamics analysis, research body segment inertia parameter identification method, and the simulation and experimental research, and developed the small gravity increase institutions, can well realize the gravity at the same time increase the effect.
