Abstract: A major concern for new generations of large turbine blades is forced and self-excited (flutter) vibrations, which can cause high-cycle fatigue (HCF). The design of friction joints is a commonly applied strategy for ...

Abstract: Considering rotational speed-dependent stiffness for vibrational analysis of friction-damped bladed disk models has proven to lead to significant improvements in nonlinear frequency response curve computations. The accuracy ...

Abstract: A model order reduction method based on the component mode synthesis for mistuned bladed disks is introduced, with one component for the disk and one component for each blade. The interface between the components at the ...

Abstract: Casings of machinery and support structures have an influence on the rotordynamic behavior, which is commonly considered by simplified models (e.g., one degree-of-freedom models). These are in many cases insufficient. ...
