Project Description

High deflection shock and vibration isolators for medium-weight sensitive equipment.

Barry VHC-Series mounts are special purpose, mid-frequency isolators designed to protect sensitive equipment when high level shock and vibration inputs are expected. Typical applications include electronic equipment installed in mobile equipment subjected to off-road environments.

VHC Mount | Dimensions and Performance

FEATURES

  • Buckling design
  • Steel construction
  • Compression to shear stiffness ratio 2:1
  • Designed to carry static loads in the axial direction, but can accommodate dynamic inputs in the radial direction
  • Attenuates 18″ freefall shock input to approximately 12g’s

BENEFITS

  • Large deflection capacity provides superior shock attenuation
  • Can be used as stabilizers for tall equipment packages
  • Maximum loads apply when mount will be subjected to an 18″ freefall. Larger loads can be accommodated for less severe shock inputs.

LOAD RANGE

  • 4 load ratings to 145 lbs. per mount

APPLICATIONS

  • Ground vehicle electronics
  • Shipboard equipment
  • Shipping containers
  • Equipment installed in transportable shelters

ENVIRONMENTAL DATA

  • Barry LT (low-temperature) Compound, which is ideal for military applications, operates between -67°F and +180°F (-55°C to +82°C) and is resistant to fungus and ozone.
  • Neoprene has an operating temperature range of -20°F to +180°F (-30°C to +180°C) and resists oil and ozone.
