AI Technical Summary

Technical Problem

Existing control systems for constructing tapered structures, such as wind turbine towers, fail to facilitate the continuous and accurate formation of spiral-welded tapered structures due to additional degrees of freedom and complexity in manufacturing.

Method used

A control system that coordinates the infeed, curving, joining, and runout systems to ensure purely rotational motion of the stock material, using adjustable rollers and steerable rollettes to form a tapered structure with a continuously changing diameter, minimizing gaps and overlaps.

Benefits of technology

Enables the precise and error-free construction of tapered structures by controlling the curvature and alignment of the stock material, ensuring consistent quality and reducing manufacturing defects.
