An Ergonomic Evaluation of the Extravehicular Mobility Unit (EMU) Spacesuit Hard Upper Torso (HUT) Size Effect on Mobility, Strength, and Metabolic Performance

摘要

The objective of this project was to develop a comprehensive methodology to assess the suitfit and performance differences between a nominally sized extravehicular mobility unit (EMU) spacesuitand a nominal +1 (plus) sized EMU. Method: This study considered a multitude of evaluation metrics including3D clearances and pressure point mapping to quantify potential issues associated with using offnominalsuit sizes. Results: There were minimal differences with using a plus suit size. Discussion: Analysisof the results indicates that future suit size evaluations should consider this ergonomic approach to understandand mitigate potential suit fit and performance issues.
