Die Windgeschwindigkeiten schwanken st\u00e4ndig und induzieren dadurch zyklische Zug- und Druckbelastungen der verschraubten Verbindungen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Die wiederholte Belastung erh\u00f6ht die Wahrscheinlichkeit von <strong>Schraubenerm\u00fcdungsversagen<\/strong>.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Allm\u00e4hlich bilden sich winzige Risse im Material, die sich ausbreiten, bis sie das kritische Niveau f\u00fcr einen Bruch erreichen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Erm\u00fcdungsversagen tritt h\u00e4ufig bei Turmflanschschrauben, Blattschrauben und Gondelverbindungen auf.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dies erschwert die Erkennung w\u00e4hrend der routinem\u00e4\u00dfigen Wartung.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In vielen F\u00e4llen beginnen Risse an Gewindewurzeln oder Oberfl\u00e4chenfehlern, wo sich die Spannung konzentriert.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Bestimmte Turbinenverbindungen erfahren h\u00f6here Erm\u00fcdungsbelastungen als andere.
