Abstract

We proposed a biomechanical framework for modeling human-spacesuit arm interaction while carrying out EVAs. In the model, there is detailed definition of spacesuit joint rotations, included spacesuit joint stiffness model and a delicate human arm musculoskeletal model in the Anybody Modeling System. The framework is able to predict human joint torque, muscle forces and joint reactions in various positions and postures while wearing spacesuit. Based on the predicted maximum muscle force, we made an evaluation of the comfort scale in various positions in the reach envelope. The predicted most comfortable area was compared to measured most comfortable area for model prediction validation.
