Wind power equipment simulation differs from general structural analysis—it requires balancing ultra-long service life, complex aerodynamic loads, and large-scale flexible structures. The larger the blade, the more pronounced the effects of manufacturing variation, material variability, and in-service fatigue.
Industry Characteristics
- Complex composite laminate design
- Aerodynamic loads vary continuously with wind conditions
- High requirements for life-cycle cost and O&M accessibility
Key Tasks
- Blade aerodynamic performance and load analysis
- Composite layup, shear web, and joint region strength assessment
- Fatigue life and damage propagation analysis
- Safety verification under extreme wind conditions and parked scenarios
Recommended Approach
Methodologically, a complete chain should be established from aerodynamic loading to structural response and then to fatigue life. For large blades, static strength verification alone is far from sufficient—attention must also be paid to manufacturing deviations, local delamination, and stress concentrations in edge regions.
Business Value
When blade simulation is truly closed-loop with design, manufacturing, and O&M, organizations can identify lifetime weak points earlier and more readily introduce new materials and layup schemes into production.
