simulation transport random vibrate testing system

  • Vibration

    A random (all frequencies at once) test is generally considered to more closely replicate a real world environment, such as road inputs to a moving automobile. Most vibration testing is conducted in a 'single DUT axis' at a time, even though most real world vibration occurs in various axes simultaneously.
