What is it about?
By using the weight and structure adjustment of the rotor part in the direct-drive drive-train of the wind turbine, the vibration of the drive-train system can be analysed and controlled. both deformation and forces from the system to the nacelle are discussed.

Why is it important?
the discussed direct-drive drive-train system in a offshore floating wind turbine is a new developed technology and only few researches have studied it. the presented mathematics model can show the vibration of the system clearly and provide optimizations on the structure design. Further more, the study can be extended to the vibration analysis of the whole wind turbine, such as tower system and platform system.
Perspectives
Writing this article was a starting of my study in the area about the wind turbine. I hope it can show people who has interest in this area an easy understanding of the direct-drive drive-train and how it works. Since the drive-train system has been studied individually, combined study with other system in the wind turbine will be extended in further paper to show a fully view of offshore direct-drive wind turbine.
