| 摘 要: |
Wind energy plays a crucial role in mitigating the environmental impact of modern society. As reliance on wind energy grows, ensuring the structural integrity of wind turbine blades becomes increasingly important. This is the main driving motivation for the development of advanced monitoring and modelling techniques capable of providing accurate and efficient predictions of blade behaviour. This study focuses on the application of finite element modelling to characterise wind turbine blades, with particular emphasis on the DTU 10MW Reference Wind Turbine - a shell model of an 89.2 m blade. The structural response of the blade is examined under various loading conditions, with increasing model complexity achieved through the incorporation of nonlinear effects and damage mechanisms. Using Hashin's damage criterion and the energy dissipation-based damage evolution law, a progressive failure analysis reveals valuable insights into localised damage regions and stress concentrations. These findings highlight the need for further refinement to enhance model accuracy and reliability.
风能在减轻现代社会对环境影响方面发挥着至关重要的作用。随着对风能的依赖日益增加,确保风力涡轮机叶片结构完整性变得愈发重要。这正是推动开发先进监测与建模技术的主要动力,以实现对叶片行为的准确高效预测。本研究聚焦于有限元建模在风力涡轮机叶片表征中的应用,特别以丹麦技术大学(DTU)10兆瓦参考风力涡轮机为例,该模型为一根89.2米长叶片的壳体结构。研究分析了叶片在不同载荷条件下的结构响应,并通过引入非线性效应和损伤机制,逐步提升模型复杂度。基于哈辛损伤准则及能量耗散型损伤演化规律,采用渐进失效分析方法,揭示了局部损伤区域与应力集中情况。这些发现凸显了进一步优化模型以提高其精度和可靠性的必要性。 |
