New prototypes of offshore wind turbines have been developed; not only has the power output been increased but also their sizes have become larger. However, the distinct offshore environmental loads may significantly affect the performance of the offshore wind turbines. This presentation gives the recent research results on the vibration behaviors of the multi-system involved in a spar type offshore direct-drive wind turbine. Three new models about each main component: direct-drive drive-train system, floating platform and the tower structure are first presented. Then a combined model of a spar-type floating platform wind turbine under deep-sea conditions is developed. The dynamic interaction between the drive-train system and the nacelle is considered by incorporating the modelling of the drive-train system. The hydrodynamic and aerodynamic excitations on the structures are considered, including current, wave, and wind excitations as well as buoyant forces. The effects of both hydrodynamic and aerodynamic excitations along with the dynamic interaction are investigated under different sea conditions.


Professor Ji is currently an associate professor in the School of Mechanical and Mechatronic Engineering, University of Technology Sydney. He is an internationally recognized expert in the general areas of nonlinear dynamics, vibration and control of mechanical systems. He has published more than 85 journal papers in top SCI international journals.

Professor Ji has been involved in a wide range of research projects which were financially supported by various government funding agencies, in the fields of dynamic modeling, vibration analysis, vibration control, fatigue analysis, stability analysis, FEM analysis, and the control of networked robotic systems. His research has attracted external funding of more than AUD$3.1 million.

Professor Ji is an Associate Editor for two international journals including International Journal of Bifurcation and Chaos. He is also an assessor and external reviewer for Australian Research Council ARC grant applications, Hong Kong RGC grant applications, and European Grant applications. He has been a session chair and also presented his research results in many key international conferences. He is the chairman for the organizing committee of the 18th Asian-Pacific Vibration Conference (www.APVC2019.org) to be held in Nov 2019 in Sydney Australia.
