Human Motion Simulation and Analysis in Microgravity Environment Based on ADAMS
Microgravity has significant influence on the astronaut’s extravehicular tasks in space environment. This paper proposes an ADAMS based human motion simulation method to analyze the force and torque changes due to microgravity. According to basic theory of human anatomy, a human rigid model is built using SolidWorks 3D modeling software considering the human bones, joints and muscles structures, as well as the functions and pattern of motion of the body. The model refers to the 90 percentile of Chinese human body data, and keep all the main joints, in which the degree of freedom is considered to make sure the model design is reasonable and practical. Then the rigid model is imported into the ADAMS software by setting constraint, load and the motion angle to perform the dynamic analysis of the human body during one walking cycle. The force and torque of joints of shoulder, hip, knee and ankle are compared in normal gravity and microgravity environment. This paper provides necessary dynamic data for astronaut’s outer space training to optimize the operation ability when accomplishing space missions.
