CHANGES TO DEFAULT GEOMETRIC STIFFNESS
MODEL IN BLADED
studies have shown that, in some cases, the default modelling settings
in Bladed were not giving accurate results.
Bladed’s geometric stiffness model gives a first order non-linear
enhancement of the blade dynamic response. In Bladed 4.5-4.7, the
effect of element shear forces was included in the geometric stiffness
calculation. However, studies have since shown that, for many blade
designs, the geometric stiffness shear forces has a detrimental effect
on simulation accuracy and stability. Therefore the geometric stiffness
model default setting has been changed from “full” to “axial only” in
details are available here.
Bladed user conference 2016
the success of past events, the third annual European Bladed user
conference will take place on 10 November 2016 in Hamburg, Germany. It
provides a unique opportunity to present your recent work using Bladed,
meet the software developers to discuss your needs and shape the future
of Bladed, and engage with your peers within the wind turbine design
