Structural Modeling and Analysis of a Wave Energy Converter Applying Dynamical Substructuring Method
This paper deals with structural modeling and analysis of a wave energy converter. The device, called Wavestar, is a bottom fixed structure, located in a shallow water environment at the Danish Northwest coast. The analysis is concentrated on a single float and its structural arm which connects the...
