Wind turbines are exposed to particular stresses. At first glance, stability during heavy storms and hurricanes seems to be the main problem. However, the continuous, alternating loads - even in normal wind conditions - are just as problematic. Alternating loads are harder to bear than static loads, they “fatigue” the material.

摘要

Wind turbines are exposed to particular stresses. At first glance, stability during heavy storms and hurricanes seems to be the main problem. However, the continuous, alternating loads - even in normal wind conditions - are just as problematic. Alternating loads are harder to bear than static loads, they “fatigue” the material.
