Vibration Test

 

 

The Vibration shall be performed in accordance with MIL-STD-810F, Method 514, Procedure I, Category 24 (Minimum Integrity Test) for the non-operational condition and Category 20 (Ground Vehicles) for the operational condition. The unit should be clamped to an aluminum plate (approximating rigid mounting), and subjects to the following levels of vibration:

Non-Operational (from Figure 514.5C-17 of MIL-STD-810F) 0.04 g2 /Hz at 20-1000 Hz, -6 dB/Octave at 1000-2000 Hz, 1 hour/axis duration.

Operational (Figure 514.5C-1 of MIL-STD-810F) 0.001 g2 /Hz at 12.5 Hz, 0.034 g2 /Hz at 20~40 Hz 5.70E-06 g2 /Hz at 200 Hz, 1 hour/axis duration simulating 1000 miles of transportation.

The hard disk drive was spinning during the operational test. A functional test was performed between each axis of testing, to catch any potential failures. The operational test was conducted using the vertical axis power spectral density (worst case condition for amplitude), as the orientation of the test item during transportation is not known.

Results
All units passed the vibration test without incident.



Picture This
Day in and day out, you're continuously driving under challenging road conditions. Your notebook rides with you through it all...bumps, bounces, everyday wear and tear. If your notebook cannot withstand the necessary rigors of an in-vehicle operation, you will not be able to efficiently and effectively do your job the way it should be done.

The vibration inherent in moving vehicles can wreak havoc on average notebooks. Demand for in-vehicle computing solutions continues to grow. Through advanced testing, Panasonic confirmed that Toughbook 29 proves to be more capable of operating successfully under these conditions.


Shock-mounted HDDs
All Toughbook hard disk drives are mounted in shock-absorbing polymer compounds insulating the HDD from vibration and shock, while protecting your mission-critical data.


Vibration-resistant LCDs
To prevent costly damage to the LCD display, internal dampeners prevent damage by absorbing shock and sudden impact.


Flexible Internal Connectors
Should the notebook be dropped or bumped, flexible connectors between the hard disk drive and system board protect against the transfer of shock between these components.


Ruggedized Docking Connector
The port replicator connection on the Toughbook 29 has been ruggedized to avoid damage from the bumps, knocks and vibrations that are inevitable when operating in a moving vehicle. They stand up to installations that require unit removal and repetitive use.


Magnesium Casing
Every Toughbook features a full or partial magnesium case to assuring superior resistance to exterior effects like bumps, drops and knocks.
