Abstract
Based on the feature that offshore wind turbine tower supporting structures are affected by soil foundation and the ocean flow, the paper carries out research on supporting system structure with multi-medium coupling. Based on considering fluid-solid coupling, the paper discusses the effect of seabed soil foundation elastic conditions on tower's dynamic characteristics. The comprehensive analytical result of dynamic characteristics with soil-fluid-solid coupling is given in the end and the change law is got preliminary. The findings will provide an important fundamental basis on the anti-vibration design of offshore wind farms tower supporting structure and further research.
