Overview of The Blade Flexibility Options

Bladed utilises a finite element (FE) model to simulate the flexibility of the blades. Additionally, it can incorporate a modal reduction technique to enhance computational efficiency. To account for the non-linear behaviour of larger blades, Bladed offers several geometric stiffness models and supports the definition of multi-part blades.

Users have the option to model the blades in three different ways. These are located in the Modelling property of the Blade component, which includes the following BladeModellingType options:

  • FiniteElementBladeModelling: This approach involves structural modelling of the blade using finite element analysis without modal reduction.
  • ModalBladeModelling: In this method, the blade’s structural modelling combines a finite element model with modal reduction.
  • RigidBladeModelling: Option to make the blade completely rigid.

Changing between these three options allows for a convenient way of changing between rigid, modal reduced, or complete finite element blades.
