Abstract

The flexible system of wind turbines refers to the components such as blades, towers, and rotor shafts that are subjected to external forces such as wind loads, inertial forces, and gravity during operation, resulting in deformation and vibration. This paper proposes that dynamic response analysis of the flexible system, through the response data, put forward improvement measures to improve the stability. The flexible dynamic response of wind turbine was analyzed. The fluid dynamics and structural dynamics of wind turbine are analyzed by the finite element method, and the flow chart is combined to get the wind turbine velocity, pressure, shear stress, and vorticity distribution nephogram. The results provide a reference value for monitoring structural state dynamics parameters of large wind turbines. Wind power generation technology is relatively mature, and its proportion in the field of power generation is gradually increasing. Wind energy is inexhaustible and can occupy a place in the development and utilization of new energy for a long time. This study provides an important reference for determining the dynamic parameters of wind turbine operation and improves the stability and reliability of wind turbine operation. The results provide a reference value for monitoring structural state dynamics parameters of large wind turbines.

5 兆瓦风力涡轮机刚柔耦合多体动力学研究

风力发电机组的柔性系统是指叶片、塔架、转子轴等部件在运行过程中受到风载荷、惯性力、重力等外力作用而产生变形和振动。本文提出对柔性系统进行动态响应分析，通过响应数据提出改进措施，提高稳定性。本文分析了风力发电机的柔性动态响应。采用有限元法对风力发电机的流体动力学和结构动力学进行分析，并结合流程图得到风力发电机的速度、压力、剪应力和涡度分布焓图。研究结果为监测大型风力发电机的结构状态动力学参数提供了参考值。风力发电技术已相对成熟，在发电领域所占比重逐渐增大。风能取之不尽，用之不竭，在新能源的开发利用中长期占有一席之地。本研究为确定风力发电机组运行动态参数提供了重要参考，提高了风力发电机组运行的稳定性和可靠性。研究结果为大型风力发电机组结构状态动态参数监测提供了参考价值。

期刊介绍： Energy Science & Engineering is a peer reviewed, open access journal dedicated to fundamental and applied research on energy and supply and use. Published as a co-operative venture of Wiley and SCI (Society of Chemical Industry), the journal offers authors a fast route to publication and the ability to share their research with the widest possible audience of scientists, professionals and other interested people across the globe. Securing an affordable and low carbon energy supply is a critical challenge of the 21st century and the solutions will require collaboration between scientists and engineers worldwide. This new journal aims to facilitate collaboration and spark innovation in energy research and development. Due to the importance of this topic to society and economic development the journal will give priority to quality research papers that are accessible to a broad readership and discuss sustainable, state-of-the art approaches to shaping the future of energy. This multidisciplinary journal will appeal to all researchers and professionals working in any area of energy in academia, industry or government, including scientists, engineers, consultants, policy-makers, government officials, economists and corporate organisations.
