Simulation study demonstrates reduced deformation and stress in pre-twisted composite wind turbine blades, highlighting optimal multi-layer laminate design for enhanced structural safety.

Key Points

To optimize the vibration characteristics, tip deformation, and maximum stress of a pre-twisted composite wind turbine blade based on the NACA 4412 airfoil.
Simulated structural responses across 4, 8, 12, and 16 composite laminate layers under operational loads using ANSYS Workbench 2025 R1.
Applied the Taguchi method to design experiments across three factors at four levels to reduce computational trials.
Conducted multi-objective optimization to minimize tip deformation and maximum stress while preserving structural safety.
Force application distance exerted the largest influence on blade structural response, followed by laminate configuration and force magnitude.
A configuration of 15 N force, 60 cm force distance, and 12 laminate layers achieved an optimal composite desirability score of 0.9413.
