Abstract

This paper describes the initial development of a method for the analysis of a generic flexible membrane Wave Energy Converter (WEC). The method considers nonlinear hyperelastic effects in the calculation of the static shape and linear effects only in the system dynamics, although nonlinear effects are planned for future versions. The proposed method for calculation of the linear system dynamics is based on the standard frequency-domain method for analysis of rigid body WECs with extensions to include the effect of the internal domain, the membrane motion, and PTO. The method aims to reduce the complexity of flexible membrane WEC analysis to allow for a more thorough exploration of the potential of flexible membrane WECs, which could allow for a reduction in cost compared with rigid body WECs. Some initial results are shown for partial implementation of the method which highlights its ability to model a generic flexible membrane WEC.
