Benefits of technology
[0003]According to one aspect of the invention, a wind turbine component having a lightweight structure is provided and includes a metallic matrix defining a cavity, metallic foam enclosed within the cavity and a solidification metallurgical bond formed at an entire interface between the metallic matrix and the metallic foam.
[0004]According to another aspect of the invention, a method to form a wind turbine component configured to have a lightweight structure is provided and includes shaping a mold cavity between metallic foam and an exterior mold, filling a molten metallic matrix into the mold cavity to enclose the metallic foam and, as the molten metallic matrix cools, forming a solidification metallurgical bond at an entire interface between the metallic matrix and the metallic foam.
[0005]According to yet another aspect of the invention, a method to form a wind turbine component configured to have a lightweight structure is provided and includes shaping a mold cavity within a metallic matrix having an opening, filling the mold cavity with molten metallic material and a foaming agent, closing the opening such that the metallic matrix encloses the mold cavity and, as the molten metallic material cools and foams within the mold cavity, forming a solidification metallurgical bond at an entire interface between the metallic matrix and the metallic foam.
Problems solved by technology
Wind turbine powertrain components are often subject to large vibrational stresses.
These vibrations can lead to premature failure of powertrain components and significant noise generation.

Embodiment Construction
[0019]In accordance with aspects, a vibration damping noise reduction lightweight structure is provided for use as a multi-ton component of various types of apparatuses. These apparatuses may include, for example, wind turbines and similar components of power generation plants. The lightweight structure may include, for example, hollow tubing and / or castings of metallic materials filled by foams of metallic materials with a solidification metallurgical bond formed at an entire interface between the metallic materials and the foams.
[0020]With reference now to FIG. 1, a wind turbine component configured to have a lightweight structure 10 to provide vibration damping and noise reduction is provided. The lightweight structure 10 includes a metallic matrix 20 formed to define a cavity 21, metallic foam 30 enclosed within the cavity 21 and a solidification metallurgical bond 40. The metallic matrix 20 may include any metal or metal alloy, such as, for example, aluminum, magnesium, iron, n...
