Application of Pierson-Moskowitz wave spectrum to solution differential equations of multihull vessel

Abstract

Motion of a dynamic system can be generated by different external or internal factors. At mathematical modelling external excitation factors of the most significant effect on the system, are selected. Such external factors are usually called excitations. Response of the system to given excitations is mathematically characterized by a definite transformation called operator of a system. For a broad class of dynamic systems the relation between excitations and response is characterized by differential equations of motion. Dynamic mechanical systems which represent floating objects are tightly associated with stochastic processes. State variables and input parameters of the models are of probabilistic character. Mathematical models of such systems are represented by sets of stochastic differential equations, and form sets of Ito equations.
