风波联合作用于海上风力机的动力响应是一个复杂的非线性问题。以海上风力机为研究对象,利用数值模拟和现场实测手段,以海风和海波载荷作为载荷输入条件,建立风轮载荷模型、塔体海风载荷模型、海波载荷模型和风波联合作用下的结构动力学方程。研究海上风力机在风波联合作用下的结构动力响应和动态特性。研究结果表明,风波的联合作用对海上风力机正常工作存在一定影响,为今后海上风力机动态特性评估提供了计算方法。
The combined effect of storm on the dynamic response of offshore wind turbines is a complex nonlinear problem. Taking the offshore wind turbine as the research object, using the numerical simulation and on-the-spot measurement, taking the sea breeze and the sea wave load as the input conditions of the load, the wind turbine load model, the tower body sea breeze load model, the sea wave load model, Kinetic equations. The structural dynamic response and dynamic characteristics of the offshore wind turbine under storm-induced interaction are studied. The results show that the combined effect of the wind wave has some influence on the normal operation of the offshore wind turbine and provides a calculation method for the future dynamic performance assessment of the offshore wind turbine.
