PROVIDING CREWMEMBERS LIFE SUPPORT SYSTEMS IN VARIOUS EXTREME ENVIRONMENTS  SUCH AS MICROGRAVITY  THE MOON  AND MARS  IN THE FORM OF EXTRAVEHICULAR ACTIVITY (EVA) SPACESUITS. CRITICAL TO MISSION SUCCESS IS THE ABILITY FOR CREWMEMBERS TO SUCCESSFULLY PERFORM A SERIES OF MISSION-RELATED OPERATIONAL TASKS WHILE MITIGATING RISKS TO HEALTH AND INJURY. THEREFORE  METHODS FOR EVALUATING SUITED HUMAN PERFORMANCE AND SPACESUIT DESIGN NEED TO INCORPORATE COMPLEX MISSION RELATED DYNAMICS  SUCH AS OPERATIONALLY RELEVANT TASKS. IMPORTANT TO SUITED EVA PERFORMANCE IS MINIMIZING THE RISK TO CREW HEALTH TO AVOID CREWMEMBER OVEREXERTION AND INJURY AND ENSURE MISSION SUCCESS. THE PROPOSED METHOD WILL DEVELOP AND VALIDATE QUANTITATIVE METRICS FOR DECISIONS THAT ARE CURRENTLY MADE QUALITATIVELY WITH REGARD TO A SPACESUIT DESIGN'S RISK TO ASTRONAUT HEALTH AND INJURY DURING EVA OPERATIONS. PROBLEM STATEMENT: THERE ARE CURRENTLY NO QUANTITATIVE METHODS FOR COMPUTING THE HEALTH AND INJURY RISK TO SUITED CREWMEMBERS IN OPERATIONALLY RELEVANT SETTINGS. UNDERSTANDING THE MOBILITY AND PERFORMANCE NEEDS OF ASTRONAUTS DURING EVA AIDS IN MITIGATING THE JEOPARDY TO CREW MEMBER HEALTH. THIS REQUIRES A QUANTITATIVE TOOLSET FOR COMPARING AND EVALUATING CURRENT AND FUTURE HUMAN SPACESUIT PERFORMANCE AS A MEANS OF DESIGNING INNOVATIVE FUTURE SPACESUITS THAT MITIGATE THESE RISKS TO CREWMEMBER HEALTH. RESEARCH PLAN: A STANDARDIZED METHOD FOR EVALUATING EVA PERFORMANCE AND INJURY RISK PROVIDES METHODOLOGY FOR INNOVATING AND ROBUSTNESS FOR DEFINING THE REQUIREMENTS OF FUTURE SPACESUIT SYSTEMS. INCLUSION OF USER AND DECISION MAKER NEEDS IN THE EVALUATION PROCESSES MAXIMIZES USABILITY  UNDERSTANDING  AND IMPLEMENTATION OF NOVEL EVALUATION METHODS  EXPEDITING THE DESIGN ITERATIONS OF FUTURE SYSTEMS AND THE UNDERSTANDING OF HUMAN SPACESUIT PERFORMANCE. TO THIS END  THE SPECIFIC AIMS OF THIS STUDY ARE AS FOLLOWS: AIM 1: USE OF COGNITIVE TASK ANALYSIS TO DETERMINE A SERIES OF OPERATIONALLY RELEVANT ASSESSMENTS  TASKS  NEEDS FOR DECISION MAKERS DURING THE EVALUATION OF HUMAN SPACESUIT PERFORMANCE IN THE CONTEXT OF DEFINING SPACESUIT DESIGN REQUIREMENTS FOR MINIMIZING RISK TO CREW HEALTH. AIM 2: CREATION OF APPROPRIATE NEW PERFORMANCE METRICS AND DATA ACQUISITION MODALITIES TO QUANTIFY PERFORMANCE DURING OPERATIONALLY RELEVANT TASKS. AIM 3: VALIDATION OF OPERATIONALLY RELEVANT  QUANTITATIVE PERFORMANCE METRICS WITH OPERATIONAL DECISION MAKERS. IMPACT: THE PROPOSED FRAMEWORK ENABLES A STANDARDIZED METHOD TO DETERMINE AN ASTRONAUT'S RISK TO HEALTH AND INJURY DURING EVA OPERATIONS. THESE METRICS CAN THEN BE USED BY SUIT DESIGN ENGINEERS TO MAKE DECISIONS ON THE APPROPRIATE \"DO NOT HARM\" REQUIREMENTS FOR CURRENT AND FUTURE SPACESUIT DESIGNS.","funder_award_id":"NNX16AM71H","funder_id":"https://openalex.org/F4320306101","funder_display_name":"National Aeronautics and Space Administration"},{"id":"https://openalex.org/G6609051410","display_name":"THE RESEARCH OBJECTIVE OF THE PROPOSED EFFORT IS TO COUPLE FINITE ELEMENT AND MUSCULOSKELETAL MODELING TO ENABLE SIMULATION BASED DESIGN OF HUMAN EXOSUIT SYSTEMS  AND TO USE THIS FRAMEWORK TO EVALUATE OPERATIONAL PERFORMANCE SENSITIVITY TO PARAMETER CHANGES. THIS WORK BRIDGES THE DOMAINS OF BIOMECHANICS  HUMAN FACTORS  AND COMPUTATIONAL SOLID MECHANICS TO CREATE A MODEL BASED ENGINEERING APPROACH TO ANSWERING RELEVANT RESEARCH QUESTIONS. MANY CHALLENGES EXIST IN SIMULATING THE DYNAMICS OF TIGHTLY COUPLED SYSTEMS  SUCH AS EXOSKELETONS OR EXOSUITS AND HUMAN OPERATORS. THERE ARE CURRENTLY NO HIGH FIDELITY MODELS THAT ATTAIN ACCURATE REPRESENTATIONS OF BOTH A HUMAN OPERATOR AND WEARABLE DEVICE. ENABLING SYNERGISTICALLY INTEGRATED WEARABLE SYSTEM DESIGNS THAT AUGMENT PERFORMANCE  REQUIRES A TOOL TO EVALUATE DYNAMIC MOBILITY AND AGILITY OF THE HUMAN SUIT SYSTEM  IN PARTICULAR THE UNDERLYING HUMAN MOVEMENTS THAT GENERATE THE SUIT MOTIONS  THE SURFACE INTERACTION FORCES AND DEFLECTIONS  AND THE CORRESPONDING JOINT TORQUES. THIS EFFORT WILL FOCUS ON THREE AIMS THAT ARE DEMONSTRATED WITH THE APPLICATION OF EXTENDING EXPLORATION EXOSUIT MOBILITY 1 DEVELOPMENT OF A COUPLED FINITE ELEMENT AND MUSCULOSKELETAL MODELING OF THE INTEGRATED HUMAN SUIT SYSTEM 2 VALIDATION OF THE INTEGRATED HUMAN SUIT MODEL WITH COMPONENT LEVEL AND HUMAN SYSTEM EXPERIMENTAL DATA AND 3 EVALUATION OF OPERATIONAL PERFORMANCE SENSITIVITY TO CHANGES IN MATERIAL STIFFNESS  MUSCLE ACTIVATION ASSUMPTIONS  AND STRATEGICALLY PLACED ACTUATION. THE PROPOSED EFFORT WILL ADDRESS THE PROJECT AIMS BY IMPLEMENTING A MULTI TIERED MODEL FRAMEWORK TO CALCULATE INTERACTION FORCES BETWEEN THE HUMAN AND SUIT WITH CORRESPONDING SURFACE DEFLECTIONS AND PERTINENT JOINT TORQUES  PERFORMING A HUMAN STUDY TO VALIDATE THE MODEL ASSUMPTIONS  AND ANALYZING SENSITIVITY TO A SUBSET OF MODEL PARAMETERS.","funder_award_id":"NNX15AR20G","funder_id":"https://openalex.org/F4320306101","funder_display_name":"National Aeronautics and Space
