Response of Seated and Standing Manikin During Shock Trials on U.S.S. MOBILE BAY (GC53) AND U.S.S. ROOSEVELT (CVN71)

Abstract : The response of seated and standing manikins to shock generated during shock trials on U.S.S. MOBILE BAY (CG53) and U.S.S. ROOSEVELT (CVN71) were studied. It was found that the deck motion in the CIC compartment of CG53 was largely in the z or upwardly directed vector. However in addition to this gross heaving there was superimposed a large relatively undamped 10 Hertz oscillation. Such motion could have significant influence on injury production and seriously compromise current protective design for seated personnel. Deck motions observed on the CVN71 contained, in addition to large z direction components, almost equally, large x (surge) and y (sway) components which could contribute significantly to injury production for unprotected personnel and seriously compromise the effectiveness of current equipment design for personnel protection against ship shock motions.
