IEC 61400-8:2024概述了风力涡轮机机舱结构设计的最低要求，并不打算用作完整的设计规范或说明手册。本文件重点介绍机舱内和附近构成的结构部件的结构完整性，包括轮毂、主机架、主轴、直接驱动的相关结构、变速箱结构、偏航结构连接、机舱外壳。它还涉及结构部件与控制和保护机制的连接，以及电气单元和其他机械系统的结构连接。本文件主要关注黑色金属材料- 基于机舱结构，但也可适用于其他材料

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
