The service factor supposed to consider the dynamic effects and shocks as an extra factor. But when we calculating the extreme conditions, our software considers the dynamic effects by itself. The IEC load factors (1.35 and 1.1 for different load cases) are considered as well. Therefore, I think...
I have read many of NREL documents, but I couldn't find any answer to my simple question. My question is Not only for slewing rings, but also for other types of bearing: should we consider service factors for extreme (static) conditions? You know that extreme load that is used for static...
Hi all,
I am working on the slewing rings used in the pitch system of wind turbines.
We have calculated the tilting moments and axial loads for the following load cases:
- nominal operational condition
- maximum operational condition
- maximum downtime condition
- extreme condition
A service...
