摘要

风力涡轮机的有效机械制动器的设计一直受制于材料选择时对磨损率和摩擦系数等简单标准的依赖。在本研究中,我们提出了一种预测磨损率的新方法,即利用 Archard 磨损系数并考虑材料成分、硬度、滑动距离和轴向载荷等因素。此外,我们还开发了一个数值模型来模拟风力涡轮机刹车片的摩擦学行为,并将从混合数学模型中得出的新型磨损系数与立方和径向基函数进行了整合。这种综合方法弥补了实验数据和理论见解之间的差距,为优化刹车片设计和性能提供了一个稳健的框架。

Numerical and experimental validation of tribological phenomenon in wind turbine brake pads using novel Archard's wear coefficient
Designing effective mechanical brakes for wind turbines has been hindered by the historical reliance on simplistic criteria such as wear rate and friction coefficient for material selection. In this study, a novel approach to predicting wear rate was proposed, utilizing Archard's wear coefficient and considering factors such as material composition, hardness, sliding distance, and axial load. Furthermore, we developed a numerical model to simulate the tribological behavior of wind turbine brake pads, integrating the novel wear coefficient derived from a hybrid mathematical model with cubic and radial basis functions. This comprehensive approach bridges the gap between experimental data and theoretical insights, offering a robust framework for optimizing brake pad design and performance.
