Study on Astronaut Self-Rotation Methods in Space Flight

Abstract:

Astronauts will suffer the orientation transformation problem without external force condition in spaceflight mission. Based on the establishment of human body system dynamics equation, the recommended control methods are put forward to guide the astronauts to make their orientation changed. The movement process is simulated through use of ADAMS to confirm the feasibility of method. Finally, simulated weightlessness environment is developed to demonstrate the advantages of the recommended control method compared with other control methods. The results show that using the control methods developed in this paper will make astronauts spend less time and smaller joint torques in performing body rotation about single axis in simulated weightlessness. There has certain reference significance for astronauts to conduct orientation transformation in spaceflight.
