Resumen
This work presents a fully functioning dynamic model of a FOWT consisting on a set of second order differential equations. Resonance condition is studied in detail and the steady state response has been examined. FOWT in general have low natural frequency. Due to their geographical locations, often they are subjected to dynamic loading coming from external sources such as wind and waves. Therefore, these systems are very sensitive to a specific range of operational frequencies.
Oscillatory behavior may appear when the structure reaches its resonance condition. This work analyses the response of a FOWT model when a periodic external force is applied to it. The aim of this is to provided the basis for future investigation of self-excited vibrations in these type of systems. The computational software MATLAB has been used to analyze the BIBO stability of a FOWT model.
