The Research On Astronaut Performance In Modules By Ground Simulated Experiment

Quantitative analysis of human performance in microgravity is important for both scientific investigations and spacecraft engineering design. By collecting and evaluating the kinematic and kinetic data of astronauts in space, it becomes possible to characterize human motor strategies, postural behavior in weightlessness, improve the design of orbital modules, help maintain a quiescent microgravity environment for acceleration -sensitive science experiments, and optimize the human operative capabilities during long-duration space missions. Consequently, there is a need for a precise measurement of the forces and moments exerted by the astronauts on the space station and quantification of their postures and movements.This paper presents the design of an advanced kinematic and kinetic measurement system for Shenzhou spacecraft. This integrated system is capable to precisely measure the forces and moments the astronauts induce and their postures and movements.First, this paper induces the basic behavior of astronauts, and presents the minute project design of section-movements. Second, it presents the project design of an astronauts'kinetic measurement system that can precisely measure the forces and moments of key points on motorial person. it presents a principle and flow of the project design of an astronauts'kinetic measurement system. And it particularly discusses the demarcate of camera system, the gathering and storage of experiment pictures, pick-up of the symbol data, the parameter calculating method of target movement, and the general design of assistant equipment. Finally, it presents the planar data processing of target movement in pixel coordinates, and general precision analysis of simulated experiment.
