Shock-Mount Option for HiDAN® & HiDANplus®

The HiDAN & HiDANplus shock and vibration isolation base plate is ideal for mounting PC/104 Systems in aircraft, shipboard or vehicular applications. The system can be installed in any attitude yielding superior high frequency vibration isolation along with low resonant amplification increasing equipment reliability and extending component life. The HiDAN-Base-SM includes a flanged base plate for mounting, 4 shock mount isolators, and a bottom plate which can be assembled in any standard HiDAN or HiDANplus system.

On November 1, 1999 the RTD BME Laboratories evaluated the vibration resistance of the shock mount isolation base plate. View the white paper for the study. Several videos were taken and are available to download. Save the links below to your computer to view (note: these are large files).

History (1) of IDAN Movie (1.33MB .avi file)

• 1cm p-p 10 Hz platform vibration
  
  

History (2) of IDAN Movie (6.44MB .avi file)

• 00:00...00:22 -- Calibration of accelerometer and amplifier.
  • The acceleration is 1g RMS, 160 Hz
  • The Accelerometer sensitivity is 5 mv/g
  • Gain is 100, so 1 g means 500 mV
• 00:23...00:47 -- Random noise excitation.
  • The spectra of the platform acceleration can be seen on the spectrum analyzer,
    the voltmeter shows the 10 g RMS value.
• 00:48...00:54 -- the experimental setup
