RATIONAL DYNAMIC LOADS ANALYSIS FOR AIR CUSHION VEHICLES IN RANDOM SEAWAY OR TERRAIN

A probabilistic approach is suggested as a rational method of assessing dynamic loads prevailing on an air cushion vehicle operating in a random seaway or terrain. The hull load distributions, expressed in terms of shear force, bending moment, and torsion moment, are based on a criterion of selecting an acceptable frequency of occurrence of loading determined from the mission requirements of the vehicle. The method also includes a rational approach to the problem of combining static loads with stationary random dynamic loads (seaway or terrain) and nonstationary dynamic loads (wave slamming, terrain impact).
