Compliant offshore wind turbine foundation structure system
A compliant foundation structure system of an offshore wind driven generator adopts a supporting system of a linear spring formed by a stay cable system and a structure of a mass body formed by floating hinged bottom-supported pile legs to form a constrained rigid body motion system with two degrees of freedom. And a compliant super-flexible foundation structure supporting system of the offshore wind driven generator is constructed. Under the action of an external load, the supporting system of the compliant foundation structure of the offshore wind turbine can enable the floating pile leg to generate pitching and rolling compliant simple swing with a certain amplitude around a hinge point at the bottom of the pile leg, and through the swing motion, the huge environmental load on the floating pile leg is balanced by inertia force, so that the floating pile leg is protected from being damaged. And the balance which is usually carried out through the internal force of the structure is greatly reduced. The related cost is obviously reduced in the aspects of widening the water depth application range, simplifying the pile body structure, reducing the environmental load response of a supporting system, reducing the dependence on geological conditions, optimizing the natural vibration mode of the pile body system, simplifying the fan control strategy, avoiding dynamic cables and the like.
一种海上风力发电机顺应式基础结构系统，采用由斜拉索系统形成的线性弹簧的支撑系统与由浮式铰接坐底桩腿形成的质量体的结构，组成有约束的两自由度的刚体运动体系，构建一种海上风力发电机顺应式的“超柔性”基础结构支撑系统。在外部载荷的作用下，海上风电机的顺应式基础结构的支撑系统会使浮式桩腿绕桩腿底部铰接点产生一定幅值的纵摇与横摇顺应性的简单摇摆，通过这种摇摆运动，由惯性力平衡浮式桩腿上巨大的环境载荷，大大减低通常需要通过结构的内力来进行的平衡。在水深适用范围扩大，桩体结构简化，降低支撑系统环境载荷响应，减小对地质条件的依赖，优化桩体系统的固有振动模态，简化风机控制策略和免动态电缆等方面明显降低相关成本。
