Course Objectives
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.For whom intended
Professionals responsible for the shock and vibration integrity of equipment in Navy and other military systems - mechanical engineers and designers, analysts, COTS users, project managers, environmental test engineers and equipment packaging designers.
Technical personnel who are involved with reliability of COTS electronic equipment in Navy systems and with passing the Navy’s shock qualification processes and tests.
This course is for engineers and designers who want to
- improve their mechanical designs,
- correctly select
- isolation mounts and
- enclosures,
- learn how to analyze
- the mechanical design of their equipment and
- predict its shock and vibration response,
- understand the test requirements,
- apply workshop examples of proven designs,
- qualify their equipment (including COTS electronics),
- learn how to incorporate
- tech refresh and
- equipment upgrades
- through extension by analysis.
The focus is on commercially available isolators and enclosures and on avoiding the complexity and cost of special designs.
