DYNAMIC LOADING OF A MOTOR TORPEDO BOAT (YP 110) DURING HIGH-SPEED OPERATION IN ROUGH WATER,
Abstract
Pressures and strains were measured on the hull of a motor torpedo boat (YP110, Ex PT8) during rough-water operation in order to establish design criteria for hull plating and local structure. The most severe loading due to wave forces occurred between the forward quarterpoint and the midship section. The highest maximum effective pressure for this boat was 36 psi. In order to determine the effective pressures the solution is given for the damped response of a single-degree-of-freedom system to a modified blast pulse. Failure of portions of the hull structure during these tests indicated that previous design specifications were inadequate. In this report are proposed criteria for designing structures of sufficient local and overall strength to withstand severe dynamic loading of the type encountered in rough water. Recommendations for further research are made. (Author)
