Finite element approaches to the modelling of rotating twisted blades vibration

Popis výsledku v původním jazyce

This paper deals with the creation of the mathematical model of twisted blades, which can be further used for analyses of possible contacts in shrouding and its effects.Two main approaches exist for the modelling of twisted blades. Probably the most convenient one is the usage of special blade 1D finite elements with undeformable cross-section. The new 1D blade finite element with variable cross-section is proposed in this paper. On the other hand 3D solid finite elements can be employed using commercial finite element solvers such as ANSYS software or an in-house software can be created by in order to obtain the full control over the mathematical model and its special features.The presneted finite element models includes all effects of stationary rotation.
