On today’s battlefield the soldier is being asked to
carry more and more weight. This includes not only
the backpack weight but also that of the body armor.
This program proposed to design a composite
exoskeleton structure that ties into the existing body
armor and take the weight of that armor and
backpack from the shoulders and back and transfer
it to the waist.
The key to success of this design is that the
exoskeleton structure should sit off the shoulder with
an air gap that then carries load with minimal
deflection under compression.
Novel Hinge Concept
developed by UD-CCM
Low Cost Tooling and
Fabrication FE Design and Optimization Simplicity in Hinge Design
ACKNOWLEDGEMENTS
This work is supported by the Army
Research Laboratory through the Composite
Materials Technology program.
Decreases axial compression on the body
Protects shoulder girdle
Increases Endurance/ Performance Breathing
Efficiency and ballistic protection
Adds capability to attach equipment through
harnessing with ISS
Running, Vehicle Jump, Drop to knee, 2-4 miles running/day,
Flexibility: +/- 30° side, +/- 30° twist, -30° + 60° back/forward
Average load in Afghanistan 63-125lbs with capability to carry an injured
buddy for up to 2 hours
Worst case scenarios: 250lb man with 150lb load jumping over a 6 foot wall
landing on his feet.
Salt water immersion capable (Body sweat salt as well as sea water
environments)
Altitude 25,000ft, Thermal: 125° F (within vehicles reaching 150F), Cold - (-
40F)
Does not impede fast roping or rappelling
Requirements
Simple three part 2 pin linkage with easy
adjustment to spine or waist components for
different size soldier
Flexibility requirements in all directions met
Low cost, each element is replaceable
System can fold and is fully disassembled in
minutes
Waist components can be composite or mass
produced SMC
Pin locations are mostly in compression and
have good bearing surface area
Lightweight composite exospine structure that takes
the weight of the shoulder and translates it to the hips
