Light Weight Vehicle Structures that Absorb and Direct Destructive Energy Away from the Occupant

This project began in March 2013 and was completed by mid-2016.

Inner bulkheads configured in a model of the TARDEC V-Hull structure a.k.a. TARDEC Generic HullLighter weight vehicles is an enabling factor for faster transport, higher mobility, greater fuel conservation, higher payload and a reduced ground footprint of supporting forces. At the same time high levels of protection must be offered by the vehicle to its occupants against explosive threats. Weight reduction and high levels of survivability are mutually competing objectives.

The main objectives of this research effort is 1) to investigate the use of appropriate material properties for designing light weight structures that offer increased protection to the occupant and 2) to develop a reduced order model which can be used for evaluating rapidly a large number of alternative layered material configurations for absorbing and redirecting energy.

This work builds on a previous project that developed a multi-scale modeling technology and demonstrated that delaying and controlling the contact between a vehicle and an occupant reduces the loads developed in the occupant’s members.
