ATD Injury Metric Sensitivity and Extensibility (Completed)

Last Published: 04/20/22 11:43:24 AM (Central)

Task Book: Entry
Principal Investigator: Somers, Jeffrey

Short Title: ATD Sensitivity

Responsible HRP Element: Human Factors and Behavioral Performance

Collaborating Org(s):

Funding Status: Completed - Task completed and produced a deliverable

Procurement Mechanism(s):

Directed

Aims:
Determine the extensibility of the Test device for Human Occupant Restraint (THOR) and Hybrid III Anthropomorphic Test Device (ATD) Injury Assessment Reference Values (IARVs) to various environments and configurations

Objectives

Validate the response of each finite element model against matched physical ATD tests in the baseline seat from existing datasets.
Quantify ATD and human numerical model response variance and sensitivity to a limited set of small perturbations in seat, and restraint initial conditions.
Quantify the effects of spacecraft-specific seating and restraint configurations on ATD and human numerical model responses.

Category: Risk Characterization, Quantification
Subcategory: Evidence or Risk Characterization

Description:

Report detailing the validation of each model
Report detailing the effects of investigated loading scenarios, initial conditions, and seating configurations on injury risk and extensibility of IARVs to other designs

This study will contribute to gap closure by providing evidence of the extensibility of the IARVs to the full range of dynamic loading

Mappings

Risk of Injury from Dynamic Loads

DL-201: We do not know how load dynamics and sex differences affect injury risk in spaceflight conditions and do not have adequate injury assessment reference values (IARVs) to mitigate the increased risk of injury to the crew.

DL-301: We do not have an identified, validated and standardized approach for vehicle instrumentation and biodynamic data collection, and predictive analytic biodynamic modeling that would allow for specific risk injury prediction by mission-phase, crew functionality post-landing, and vehicle design.
