The course provides proven details of:
how to select isolators,
design isolation systems and
properly use commercial enclosures for COTS equipment,
Shock and vibration analysis methods,
equipment fragility, and
applications to MIL-S-901D and MIL-STD-167 tests,
description of the tests,
review of shock and vibration conditions and
test data from decks having natural frequencies 8 Hz, 14 Hz, 25 Hz, etc.
Can one avoid these high costs and at the same time improve the design? Successfully meeting the tests and qualifying equipment the first time through is a principal objective of this course.
The Navy's MIL-STD-901D barge test is especially severe. COTS equipment often cannot meet the shock conditions unless protected in properly designed enclosures. Isolation of equipment and how the isolation mounts and enclosure are selected and designed are extremely important. Selecting the wrong isolator can be worse than hard mounting. Shock and vibration tests are very expensive. Failure may require extensive modifications to equipment and then retest in order to validate design and equipment. Delays to the program are inevitable, costs increase rapidly and schedules can be badly affected.
