Shelter Mobility Analysis

• Structural analysis
• Vibration isolation design/analysis
• Static and dynamic modeling of transport environments
  • Road: Belgian block, Perryman cross-country, Munson gravel, washboard (Mil-Std 8090 Class V)
  • Air: C-130, C-141, C-5A, C-17
  • Rail transport
  • Sea transport
  • Handling: Crane hoist, drop shock
• Thermal analysis
• Impact analysis
• Fatigue, durability
• Noise prediction and control

Chassis modeled with solid and rigid elements; tires, suspension coils modeled by spring elements

Gichner S710 shelter mounted on HMMWV

Shelter panels modeled by laminate shell elements

Design racks for equipment isolation

Isolators modeled by spring elements at mounting locations. Equipment racks modeled as solid blocks, beams, shells

Compute modes, correlate with test measurements

Vehicle roll mode at ~ 1.3 Hz                                   Vehicle pitch mode at ~ 1.9 Hz

Assess shelter structural integrity and equipment survivability for specified loads (road transport, air transport, thermal)

Redesign as needed to achieve satisfactory margins.
