DTIC ADA114331: Simplified Shock Design for Installation of Equipment

A simplified shock design method has been developed and is set forth. The method employs the shock spectrum as the fundamental measure of both the severity of a shock environment and the hardness of a particular piece of equipment (the hardness is the equipment's capacity to survive a shock environment . Both the severity and the hardness are given as shock spectrum plots on four-coordinate paper and are thus directly comparable. The method uses a tracing method of recording the fact that the hardness exceeds the severity and thus equipment survival is assured. The report collects the extensive set of equipment hardnesses measured during the Safeguard Program and presents them in catalog form. References to other catalogs' hardnesses are given. (Author)
