HULL DEFLECTIONS DUE TO HYDRODYNAMIC LOADING ON HIGH-SPEED PLANING CRAFT
Abstract
HULL DEFLECTIONS DUE TO HYDRODYNAMIC LOADING ON HIGH-SPEED PLANING CRAFT. The goal of the proposed e ort is to gain a basic scienti c understanding of compliant plates subjected to slam events into water. The results of this research can be applied to high-speed planing ships that are subject to hydrodynamic loading from slamming into waves. The PI plans to investigate the cause and e ect relationship between the hydrody- namic loading on a plate, meant to model the bottom plating of a high-speed hull, and its response on the structure and conversely, the e ect of the structural response on the peak pressures. The three main components of this experimental research proposal include: 1. A free-falling wedge drop experiment of an aluminum/ ber composite hull to examine the full- eld, three dimensional strain eld on the ber-composite-bottom plating and correlate it with the hydrodynamic pressures on the plating. 2. A parametric study of how the thickness and type of ber lamina on the bottom plating of a free-falling ber-reinforced composite wedge a ect the strain eld and pressure loading. 3. A towed bow shape, constructed from compliant plating, through regular and irregular wave elds to simulate slamming events that the PI has previously investigated at the United States Naval Academy. In order to gain a complete understanding of these results, the measurements will be compared to the results from the Naval Academy study, and the PI will make use of the computational code, CFD-Ship Iowa, to aid in the design of the towed bow experimental study. The proposed research will involve one Ph.D. student and several undergraduate re- searchers through the independent study course o ered in the School of Naval Architecture and Marine Engineering. The student involvement will provide these students with research and professional experience and help encourage their interest of basic scienti c research and promote their thirsty to continue to expand their knowledge. This proposal supports the O ce of Naval Research Code 333: Sea Platforms and Weapons Division (R. Brizzolara). The DOD Policy Memo on Fundamental Research dated May 24, 2010 provides guidance to ensure that DoD personnel will not restrict disclosure of the results of fundamental research. Virginia Tech considers the scope of the proposed research to be fundamental research and anticipates there will be no publication approval or other requirements in the award that would restrict disclosure of the research results.
