Cong, C., 2018. Axial low cyclic loading control method for ocean wind turbine. In: Liu, Z.L. and Mi, C. (eds.), Advances in Sustainable Port and Ocean Engineering. Journal of Coastal Research, Special Issue No. 83, pp. 941–945. Coconut Creek (Florida), ISSN 0749-0208.

At present, control method of axial low cyclic loading based on PDS cannot simulate the axial load situation with high precision. To this end, this paper proposed an axial low cyclic loading control method for ocean wind turbine based on finite element. In the simulation process, the proposed method establishes the axial finite element model based on relevant modeling parameters and ANSYS. The low-speed cyclic loading and high-speed cyclic loading are added to the numerical simulation model to observe the bearing limit of the model and 60% of the ultimate bearing capacity is taken as the maximum control loading. The experimental results showed that the proposed method improves the simulation accuracy. The error between the maximum displacement of the simulation and the actual maximum displacement was not more than 7 mm, which provides support for the wind turbine bearing fault prediction.
