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:

  1. Wire chafing.

  2. Loosening of fasteners.

  3. Intermittent electrical contacts.

  4. Touching and shorting of electrical parts.

  5. Seal deformation.

  6. Component fatigue.

  7. Display / Touch Panel misalignment.

  8. Cracking and rupturing.

  9. Excessive electrical noise.

Two Vibration tests are performed on the TDS Recon, figures 17 (general) & 18 (helicopters). The minimum integrity (general) test is a Power Spectral Density = 0.04G²/Hz, 20 to 1000Hz, descending 6dB/oct to 2000Hz. Three axes are tested, 1-hour per axis. Figure 18 (helicopters) is a Logarithmic sweep 5 to 500Hz beginning at 0.20" displacement, 30 minutes per axis.
