Research on structural fatigue residual life of pitch bearing rings after pre-damage
Jixie chuandongObjectiveThe corrosion fatigue fracture of the wind turbine pitch bearing is a major failure mode, often leading to the blade detachment and shutdown. To this end, a finite element model of replacing the whole pitch bearing with a local one was proposed ...

Untersuchungen zur analytischen Restlebensdauerbestimmung thermisch belasteter dickwandiger Bauteile [PDF]
Als Konsequenz der Energiewende folgen aus der geänderten Belastung mit z.T. steileren Transienten thermomechanische Spannungen in den dickwandigen Komponenten, welche zu einem Bauteilversagen infolge Ermüdungsrisswachstum führen können.
