AI Technical Summary
Traditional wind turbine steel towers are prone to local buckling and instability when subjected to complex wind loads and external forces. Existing strengthening measures, such as increasing tower wall thickness and using high-strength steel, are costly and involve complex construction issues, which are not conducive to their widespread application.
The buckling-resistance bracing device, which adopts a sliding track and support structure, controls the movement of the support structure on the sliding track based on the buckling data of the wind turbine cylindrical steel tower through the control system. The support structure abuts against the inner wall of the wind turbine cylindrical steel tower to provide buckling resistance, and the support position is predicted and adjusted through a neural network model.
It effectively reduces material usage and manufacturing costs, lowers manufacturing difficulty, enhances the adaptability of wind turbine steel towers to various load conditions, improves structural reliability, and prevents local buckling and instability.
