On the Correlation Between the MIL-S-901 Shock Test Environment and the ANSI National Standard, Shock Test Requirements for Equipment in a Rugged Shock Environment

摘要

The shock test severity of the Mil-S-901 lightweight machine is compared with the drop tests outlined by the new proposed ANSI National Standard for equipment in a Rugged Shock Environment. Shock spectra for a resiliently mounted notebook computer are reported for the lower five ANSI drop test levels and compared to the spectra for the lightweight machine hammer drop heights of 12", 36" and 60". The resilient mounting system in the drop test series bottomed out, while it did not during the Mil-S-901 tests. It is concluded that while the drop test shock environment may not be representative of underwater explosions, it can provide a very severe ruggedness benchmark.
