Evaluation of Two Fully Rugged Laptop Computers for the Forest Service
Appendix E—Vibration Tests
Purpose
These tests were conducted to determine whether vibrations could cause electrical or mechanical problems, particularly if any joints were soldered improperly. Tests were conducted under the guidance MIL-STD-810F, Method 514.5—Procedure I (general vibration), non-operating, 60 min, one axis.
A small, commercial vibration table was used for the tests. Larger vibration tables used for testing electrical components may cost $100,000 or more.
Equipment
The table vibrated at 3,600 vibrations per minute. PassMark BurnInTest software was used to test the laptops' internal components. The touchscreen, touch pad, and keyboard were functionally tested.
Procedure
Before testing, each laptop was tested using the BurnInTest software. One laptop was placed on the table and the table was turned to its highest setting. The laptop was left on the table for 60 min. Then the laptop was started and the touch screen, touch pad, and keyboard were functionally tested. BurnInTest software was run to test the internal components.
Results
After 60 min on the vibration table, both laptops passed all tests.
Conclusions
After 60 min on the vibration table, both laptops passed all tests.
