MIL-STD-810F Method 514.5 - Vibration
Vibration testing is performed to determine the resistance of equipment to vibrational stresses expected in its shipment and application environments. Vibration can cause:
- Wire chafing.
- Loosening of fasteners.
- Intermittent electrical contacts.
- Touching and shorting of electrical parts.
- Seal deformation.
- Component fatigue.
- Display / Touch Panel misalignment.
- Cracking and rupturing.
- Excessive electrical noise.
Recon, Ranger, Nomad and Yuma all passed the following tests:
- Procedure I, General Minimum Integrity: Power Spectral Density = 0.04G²/Hz, 20 to 1000Hz, descending 6dB/oct to 2000Hz. Three axes are tested, 1-hour per axis.
- Procedure II, Vibration and Loose Cargo: a Logarithmic sweep 5 to 500Hz beginning at 0.20" displacement. Three axes are tested, 30 minutes per axis.
