Abstract
This article treats the problem of the analytical-computational determination of slamming forces, and resultant structural loads, for flat-bottom centerbody surfaces of advanced marine vehicles (such as hullborne SES, SWATH and similar catamaran vessels) in waves. The analysis uses the concept of fluid momentum theory. A three-dimensional model eliminates the infinite force behavior attaching to conventional two-dimensional strip theory methods applied to impact problems for flat surfaces. Theoretical results are in good agreement with model test data. The range of values possible in peak slamming load measurements in regular wave is discussed, as are the contributing causes for such effects.
