U.S ARMY WIAMan BLAST DUMMY

FIRST VERTICAL LOAD MANIKIN WITH INTEGRATED IN-DUMMY DAS

The Challenge:

• Improve military vehicle designs to better protect soldiers in underbody blasts
• Current automotive crash test dummies are designed for either frontal or side impact testing
• Tight space constraints in military vehicles for test instrumentation
• High channel count tests, including set-up and positioning ATDs with large umbilical of exit cables
• Cable management, issues with noise, data loss and damaged or tangled cables
• Manikin needed to withstand repeated vertical acceleration blast pulses in the lab and live fire tests
• Limited biomechanics data available to support development of a new ATD

The Solution:

• U.S. Army assembled an expert team of government, industry and academia partners
• DTS was named the Prime Contractor to develop the new ATD and a new in-dummy DAS solution
• Warrior Injury Assessment Manikin (WIAMan) is the first underbody blast dummy designed for vertical load testing
• Designed and manufactured a sophisticated, modular in-dummy DAS solution
• Required extensive biomechanics data research, utilized new ATD manufacturing techniques and materials
• Engineered to support 150+ channels of SLICE6 distributed throughout WIAMan utilizing Ethernet
• SLICE6 reduces in-dummy cabling and connectors by up to 75%, and has only a single external communications/power cable which can be disconnected for test, making the ATD fully autonomous
• Utilizing the IEEE 1588 time protocol standard for achieving clock accuracy in the sub-microsecond range for precise synchronization across all data channels both within the ATD and when using multiple ATDs in a single test
• Store in place reliability, data writes directly to non-volatile flash memory
• Proven reliability of ATD and DAS through hundreds of simulated, laboratory and live-fire tests
