Why WIAMan?

• WIAMan is the world's first test manikin that is purpose-built for military use in under-body blast (UBB) testing of ground vehicles in LFT&E

• Benefits include:– Improving soldier survivability and quality of life when subjected to

the effects of UBB– Improving the protection of ground vehicle systems– Evaluating the effects of UBB on mission-critical tasks– Quantifying the risk to the Warfighter and identifying tradeoffs

during vehicle design

DOT&E Capability Gap

• DOT&E Issue Papers and RMD700 were based on creating a DoD capability for UBB injury risk assessment that is equivalent to that used by DOT

• Current capability – based on Hybrid III –is inadequate for determining the risk of skeletal injury to vehicle-mounted Soldiers subjected to UBB threats

• Army commitment to DOT&E as presented at inaugural meeting of WIAMan SSG in Feb 2011 – Create a new military Anthropomorphic Test Device based system for under-body blast injury assessment for Title 10 LFT&E

The HIII’s lack of injury resolution and biofidelity does not support requirements development, system design, vulnerability evaluation, or the modeling and simulation of UBB events.- Dr. J Michael Gilmore,

DOT&E Issue Paper, 2013

The HIII’s verified lack of injury resolution and biofidelity in the UBB environment makes it inadequate to assess injuries in the UBB loading regime.- Dr. J Michael Gilmore, DOT&E Issue, 2015


• Test Capability Requirements Document (TCRD)– Reflects the Department of Transportation’s standard for

developing a valid ATD-based injury assessment capability

– Signed by CG ATEC and CG RDECOM; approved by DOT&E in Jan. 2016

Requirements Snapshot

KPP Description

#1: Biofidelity WIAMan shall exhibit human-like motion and load transfer when subjected to UBB loading

#2: Data Collection WIAMan shall measure and record data that correlate to UBB-related injuries

#3: Injury Assessment The relationship between WIAMan response and probability of injury shall be understood

#4: Operational Readiness WIAMan shall be available to support multiple concurrent LFT&E UBB vehicle tests

Governance

• Regular engagement with DoD and Army stakeholders through Senior Steering Group (SSG) action officers– Biweekly council of colonels meetings– Program management and technical reviews

• ASA(ALT) directs PEO STRI to adopt non-traditional, rapid system acquisition with DOT&E sponsorship– MOA signed by CG, RDECOM and PEO STRI in

Dec. 15• MOA delineates S&T and material developer

responsibilities • PEO STRI is fully integrated into S&T program

activities (technical/schedule)– Transition TRL 6 WIAMan system to PEO STRI for

material development/procurement (FY18)– Mature injury assessment capability through ongoing

biomechanics research (FY 17-FY 20)

Where Are We Today?

• Gen 1 ATD delivered on 29 June 2017– Verification, Validation, and Accreditation plan in progress – Evaluation of sensor performance

• Capacities, locations, accuracy, etc.– Data acquisition capability integration

• Injury Assessment Reference Curve Testing Underway

– BRCs completed in Feb. 2017

– TD matched-pair testing for first wave IARC creation– Injurious Biomechanical testing to maximize injury data points for first

wave HIPCs delivered 29 Sept. 2017

• Gen 1 FEM Model– Updating model to reflect Gen 1 advancements

– Pre-test simulations for ride-along opportunitiesGen 1 ATD

1. Design based on today’s Warfighter in a seated posture

2. Excellent durability to ensure repeatable injury prediction and reduced lifecycle cost

3. On-board data acquisition to reduce set-up times and eliminate cabling

• 1 mile of cable 4. Fully instrumented lower

extremities for high-fidelity UBB-centric injury prediction

5. Spine curvature allows for improved acceleration response and spinal injury assessment

6. Anatomically accurate pelvis with full instrumentation for pelvic injury prediction

1. Design based on 50th

percentile 1970s male citizen2. Poor durability compromises

reproducibility, repeat testing, and total lifecycle costs

3. Lack of on-board data acquisition; increases set-up times and requires harness

• 44 miles of cable4. Legs have no biofidelity or

sensors in foot/ankle5. Rigid design of spine prevents

assessment of spinal injury6. Pelvis does not reproduce

human response, offering no relevant instrumentation for injury prediction

WIAMan LFT&E Ride-Along Opportunities

• Participated in nine LFT&E representative tests– March 2017 – MRAP Vehicle– June/July 2017 – ARL-SLAD Modified RG31(6)– Aug. 2017 – STRYKER Vehicle (Gen 1)– Aug. 2017 – MRAP DASH Vehicle

• WIAMan ATD sustained no damage• Data successfully captured from sensors

– Head, Neck, Back, Foot and Ankle

• Set-up time of WIAMan ATD significantly reduced – Less time than Hybrid III ATD– Single cable vs. miles of cable

• Strong repeatability from test to test
