The study of an integer design and development of virtual human motion analysis software on VC platform

In order to reduce the difficulties and hazards of astronaut's extra vehicular activities(EVA), it's essential for virtual human(VH) software to apply in the studies of kinematics and dynamics simulation for EVA. Jack which used generally cannot realize the dynamic solution for VH motion at the state of weightlessness, and its costliness also reduces the interactive capacity. A concept of VH motion analysis software on VC platform is presented in this paper to solve the above problems. In this software, VH modeling is established on the basis of relative robotics, the algorithms for VH kinematics and dynamics analysis are implemented by standard C programs, and the visual simulation interface is developed by OpenGL on VC platform. The present software can realize the trajectory-planning and joint force/torque solution along the path for VH motion at the state of weightlessness, therefore, it provides reference data applied in digitized analysis of EVA accordingly, furthermore, the lower cost and friendly interface of VC software demonstrate its applicability and interactive capacity to meet the requirements.
