Dynamic response analysis of TLP”s tendon in wave and current
Tendon of TLP would have deformation along the flow direction and VIV response perpendiculars to the flow direction in current load effect.Wave load and tension changing in tendon will observably influence the VIV response.The large finite element software ANSYS and the CFD software FLUENT are used to analyze the dynamic response of TLP”s tendon in wave and current load effect.FLUENT is used to figure out the hydrodynamic forces of tendon.Morison equation is used to figure out the wave load of tendon.The hydrodynamic forces are transferred to the tendon through flow field.The tendon is considered as two tips end-fixed and its dynamic response is solved in different pretensions.The results show that the tendon has realizing transverse vibration and little vibration in current direction,but the realizing drift in current direction must be considered.
