AI Technical Summary

⚠Technical Problem

Existing small and medium-sized wind turbine tower structures suffer from complex manufacturing processes, high costs, or poor wind resistance. In particular, while tapered tube towers offer good structural stability, they are expensive, and while straight tube towers are simple to manufacture, they have poor wind resistance and significant top vibration.

⚗Method used

The tower structure adopts a combination of spiral steel pipe straight pipe and tapered pipe. By using the combination of straight pipe tower and tapered pipe tower, the spiral welded seam enhances the torsional resistance, and the connection stability is improved by connecting flanges and reinforcing ribs, thereby reducing production costs.

🎯Benefits of technology

While ensuring the stability of the tower structure, it improves production efficiency, reduces production costs, enhances torsional resistance, avoids stress concentration under alternating loads in traditional straight seam welding, and reduces top vibration.
