This paper presents a comprehensive review of the latest advancements, challenges, and future directions driven by Artificial Intelligence (AI) in the design
Validation against 6,468 simulations shows that the optimized tower extends the estimated fatigue life from 9 months to 25 years while avoiding resonance, and
# Investigating fatigue life in bolted flange connection in wind turbine towers. This study investigates the fatigue performance of bolted flange connections in wind turbine towers by examining the effects of bolt size and number under variable wind speeds. A simulation framework integrating TurbSim, FAST, and ANSYS Workbench was developed not only to evaluate fatigue behavior, but also to provide a reference methodology for future studies in similar structural applications. Results show that increasing the number of bolts leads to a nonlinear and significant improvement in fatigue life. For example, increasing M48 bolts from 120 to 160 improved fatigue life by over 1000% at a 5 m/s wind speed. An interesting hypothesis derived from the results suggests that increasing one bolt size may produce a fatigue improvement comparable to adding approximately 30 smaller bolts, highlighting a promising direction for future validation and design optimization. ### Fatigue Life Prediction for Flange Connecting Bolts of Wind Turbine Tower.

For fatigue maximum stress isn't the concern, the range of stresses induced is used to calculate fatigue life. You will need S-N (stress range
Designing the tower to have the same lifetime as other components is clearly desirable for optimization of the wind turbine system. This study
This suggests that the design of T-1 is excessively conservative compared to the original model, which has a fatigue life of approximately 36
