Services to OEMs
We help OEMs enhance aeroelastic designs to mitigate stall- and vortex-induced vibrations, fully aligned with international standards and industry best practices. We also support the design and evaluation of new technologies.
Aero-elastic analysis and design of wind turbine systems
- Proposing minor design modifications to the blade internal structure to improve aeroelastic stability performance, typically during the design phase of new platforms or blades
- Defining optimal pitch settings for installation and parked/idling conditions
- Performing aeroelastic stability analysis regarding stall-induced vibrations (SIV) and identifying low or negatively damped modes under parked/idling and assembly/maintenance conditions
- Conducting vortex-induced vibration (VIV) analysis of the entire wind turbine configuration, including tower and blade VIV for 1st and 2nd mode shapes
- Assessing loads for onshore and offshore (bottom-fixed and floating) WTGs in accordance with IEC standards.
- Assessing and co-developing new technologies
Numerical blade modal test
A novel framework to estimate the structural damping of composite structures such as blades, based on laminate properties.
- Combining a FEM solver with fully populated stiffness and damping matrices with a cross-sectional tool that prepares the required input
- Providing blade mode shapes and structural damping ratios
- Accounting for material asymmetries that introduce coupling effects, such as the ply angle offset of UD material on the spar cap
