Abstract

Forming superconducting radio frequency (SRF) cavities with hydrostatically controlled bulging, using a pressurizing incompressible medium, such as urethane elastomer, for hydroforming a metal tube in a mold. The urethane elastomer functions as the pressurizing incompressible medium in the hydroforming process. Stretch-thinning of the metal tube wall is reduced by a decrease in concentrated bending deformation thereof. Friction between the inner wall of the metal tube and the incompressible medium constrains the plastic flow of the tube wall material, thus reducing the stretch deformation and thickness reduction thereof. A stepped press ram may be used to pressurize the incompressible medium material and then pushes on an end of the tube to feed extra tube length into the expanding tube wall for reducing thinning thereof.

Abstract

Semi-submersible wind turbine platforms capable of floating on a body of water and supporting wind turbines, and a method of manufacturing the semi-submersible wind turbine platforms from advanced cementitious composite material are provided. The method includes determining at a first iteration topological outputs of the wind turbine platform including a plurality of modular sections consisting of an advanced cementitious composite (ACC) material, obtaining a second iteration from the topological outputs, the second iteration including a second model platform and a second model tower of the wind turbine platform, and obtaining addition iterations via simulation to attain a final model platform and a final model tower, the final model platform and the final model tower including a layout of the plurality of modular sections and connections for a platform and a tower of the wind turbine platform.
