摘要

除了腐蚀之外,海上风力涡轮机还受到一系列结构载荷的影响,这些结构载荷会导致动态应力,从而增加腐蚀坑的生长动力学。由于点蚀速率的显著增加,干湿阶段的交替是需要考虑的一个非常重要的因素。本文研究了干湿条件对S355G10+M结构钢剩余寿命的影响。对S355G10+M钢试样在不同轴向荷载水平下进行了模拟干湿条件下的腐蚀疲劳联合试验,并在人工形成腐蚀坑。将现有的S355钢空气疲劳数据与设计的海水自由腐蚀曲线进行了对比。此外,这些结果与文献中可用的理论模型得到的腐蚀环境的S-N曲线进行了对比。这种方法能够从现象学的角度对疲劳寿命进行评价。

The Effect of Alternating Wet-Dry Conditions in the Fatigue Life of S355G10+M Steel under Corrosion-Fatigue Testing
In addition to corrosion, offshore wind turbines are subjected to a spectrum of structural loads that lead to dynamic stresses that increase corrosion pit growth kinetics. Alternation of wet and dry stages is a very important factor to be considered, due to significant pitting corrosion rate increment. In this work, the effect of wet-dry conditions in the remaining life of structural steel S355G10+M was investigated. Combined corrosion-fatigue tests were performed in samples of S355G10+M steel with an artificially generated corrosion pit, under simulated wet-dry conditions at different axial load levels. Experimental results were compared with existing fatigue data in air of S355 steels and design curves for free corrosion in seawater. Additionally, these results were contrasted with S-N curves for corrosive environment obtained from theoretical models available in the literature. This approach enabled the evaluation of fatigue life from a phenomenological perspective.
