Resumen de: WO2024087996A1

A compliant foundation structure system for an offshore wind turbine, utilizing a structure comprising: a support system, having linear springs formed by a stay cable system; and a mass body formed by a floating hinged bottom-supported pile leg; and formed having a constrained two-degree-of-freedom rigid body motion system, thereby constructing an offshore wind turbine compliant "super-flexible" foundation structure support system. Under the action of an external load, the support system of the offshore wind turbine compliant foundation structure causes the floating pile leg to generate a compliant simple rocking about a hinge point at the bottom of the pile leg, with a certain amplitude of pitch and roll; this rocking motion allows inertial forces to balance the huge environmental load on the floating pile leg, thereby greatly reducing the balancing generally needing to be carried out by internal forces of the structure. The invention expands an applicable range of water depths, simplifies the structure of the pile body, reduces the environmental load response of the support system, reduces dependence on geological conditions, optimizes the inherent modes of vibration of the pile body system, simplifies turbine control policy, and significantly reduces costs related to aspects such as not using dynamic cables, etc.
