Discussion

This analysis reveals deformation patterns of flexible wind turbine blades under varying conditions, suggesting effective design strategies.

The dynamic behavior of wind turbine blades is effectively simulated, achieving up to 15% deformation error across wind speeds.
Under shutdown conditions, the blade tip deformation error remains within 5% with gravity alone and 8% with wind loads.
The proposed model uses high-precision engineering simplifications to analyze bending-torsion coupling in wind turbine blades.
Results validate the model’s accuracy against commercial software, highlighting its potential for early-stage dynamic analysis.

Zhu et al. (2025) studied this question.
