IEC 61400-8:2024 outlines the minimum requirements for the design of wind turbine nacelle-based structures and is not intended for use as a complete design specification or instruction manual. This document focuses on the structural integrity of the structural components constituted within and in the vicinity of the nacelle, including the hub, mainframe, main shaft, associated structures of direct-drives, gearbox structures, yaw structural connection, nacelle enclosure. It also addresses connections of the structural components to control and protection mechanisms, as well as structural connections of electrical units and other mechanical systems. This document focuses primarily on ferrous material-based nacelle structures but can apply to other materials also as appropriate lIEC 61400-8:2024 definit les exigences minimales de conception des structures deoliennes sur nacelles et nest pas destinee a servir de specification de conception complete ou de manuel dinstructions. Le present document porte sur lintegrite structurelle des composants structurels constitues a linterieur et a proximite de la nacelle, y compris le moyeu, le cadre principal, larbre principal, les structures associees dentrainement direct, les structures des boites de vitesse, la connexion structurelle dorientation, lenveloppe de la nacelle. Il traite egalement des connexions des composants structurels aux mecanismes de commande et de protection, ainsi que les connexions structurelles aux unites electriques et aux autres systemes mecaniques. Le present document concerne principalement les structures de nacelle en materiaux ferreux, mais peut egalement sappliquer a dautres materiaux, le cas echeant. La conception des assemblages boulonnes et soudes dans les structures de nacelle est incluse, ainsi que les composants coules et forges.
