Based　on　the　the　general　finite　element　program　of　ABAQUS　and　an　open-source　code　FAST　for　wind　turbine(WT)　design,　a　simulation　software　platform　ABA-OWT　for　dynamic　response　analysis　of　the　offshore　wind　turbine　(OWT)　was　developed.　The　standard　model　of　NREL　5　MW　offshore　wind　turbine　with　monopile　foundation　is　selected.　Firstly,　this　platform　realizes　the　automatic　modeling　of　the　OWT　structural　model　in　ABAQUS,　which　was　initially　verified　its　correctness　according　to　the　structural　properties　of　the　WT　provided　by　NREL.　Then,　to　create　real-time　coupling　interactions　between　the　WT　structural　model　and　various　environmental　loads　in　the　time　domain,　the　WT　structural　model　in　the　ABAQUS　was　coupled　with　the　submodules　of　aerodynamics,　hydrodynamics　and　the　control　system　(servo)　from　the　FAST　by　ABAQUS　subroutines.　Finally,　the　results　of　WT　structure　dynamic　responses　from　ABA-OWT　and　FAST　are　compared.　The　analysis　results　show　that　the　ABA-OWT　WT　structure　numerical　model　is　more　flexible　than　FAST　model.　Under　various　working　conditions,　the　dynamic　responses　of　WT　structure　from　ABA-OWT　and　FAST　are　basically　the　same;　ABA-OWT　realizes　the　dynamic　response　analysis　of　OWT　structure　under　the　combined　action　of　wind,　wave　and　servo-control　et　al.　©　2022,　Solar　Energy　Periodical　Office　Co.,　Ltd.　All　right　reserved.
