摘要

摘要: 随着风电产业快速发展以及风力叶片不断大型化,适用于更大型风力叶片测试、具有更高承载能力的大型风力叶片试验台设计与建设需求逐渐变得迫切。在此背景下,文章首先结合风力叶片试验台调研与大型风力叶片测试性能需求,分析了双倾斜加载面钢筋混凝土结构对于大型风力叶片试验台的适用性,并结合工程经验提出了相关设计参考指标。其次,依托实际工程设计对该类试验台主体结构模态以及不同加载工况下的受力特征进行了有限元模拟,明确了其承载力控制因素为混凝土最大主拉应力。最后分析了墙厚、法兰尺寸、配筋和材料等设计参数对试验台主体结构受力的影响,并基于此提出了主体结构构造优化方法。

Abstract: With the rapid development of wind power industry and the continuous upsizing of wind blades, the research needs of a test bench for the wind turbine blade with higher bearing capacity, which are suitable for larger wind turbine blades testing, have become increasingly urgent. In this context, the applicability of reinforced concrete structures with double inclined loading surface for the test bench for large wind turbine blades was analyzed based on the research of the test bench and the performance requirements of large wind turbine blade test, and the relevant design reference indexes were proposed from engineering experience. Secondly, on the basis of the engineering design, the finite element simulations were carried out on the mode of vibration and the stress characteristics under different loading conditions of the main structure of the test bench for large wind turbine blades, indicating that the control factor of the bearing capacity was the maximum principal tensile stress of the concrete. Finally, the influence of the design parameters such as wall thickness, flange size, reinforcement and material on the force of the main structure of the test bench was analyzed, leading to the proposal of optimization methods for the structural design.
