Study on Fluid-structure Interaction Characteristic for Large Scaled Wind Turbine Blade

  • 摘要: 随着大型风力机叶片尺寸增大,其柔性也越来越大,在运行中更容易出现大变形现象,进而导致叶片结构的几何非线性变形、流体的非定常特性以及独特的流固耦合现象,需要采用更准确的模型进行分析。该文采用基于几何精确梁方法和自由涡尾迹方法的流固耦合模型,研究了大尺寸叶片的耦合特性。针对叶片柔性变大、质量变轻的特点,分别采用缩小叶片刚度和质量的方法,研究叶片大变形和质量变轻对耦合响应的影响,结果表明刚度降低会大幅增大叶片变形和载荷,而质量降低对叶片变形和载荷的影响并不明显。当刚度和质量同时降低时,叶片在叶轮平面外变形量大幅增加,使叶轮功率下降。对叶片尺寸变大带来的影响也进行了研究,发现大尺寸叶片的根部应力和载荷波动会较明显高于小尺寸叶片。
