Procedures for Conducting Shock Tests on Navy Class HI (High Impact) Shock Machines for Lightweight and Mediumweight Equipments

摘要

Combat worthiness of Navy shipboard systems and equipment is in large part due to tests conducted on the Navy Class HI (High Impact) Shock Machines for Lightweight and Mediumweight Equipments. These machines are often referred to by the abbreviated names of Lightweight Shock Machine (LWSM) and Mediumweight Shock Machine (MWSM). The validity of tests performed on these machines depends on their being operated properly. The rules and guides for their proper operation, however, are scattered throughout the literature of the field, and some seem not to be documented at all. This report provides a comprehensive assembly of the rules to be followed and the guides to be observed to achieve consistent, valid tests of Navy equipment by use of the LWSM and MWSM. (Author)
