标准摘要
[中文适用范围]: IEC 61400的这一部分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操作手册。本文件关注机舱内及附近结构组件的结构完整性,包括轮毂、主框架、主轴、直接驱动相关结构、齿轮箱结构、偏航结构连接、机舱外壳。它还涉及结构组件与控制保护机制的连接,以及电气单元和其他机械系统的结构连接。本文件主要关注基于铁材料的机舱结构,但也适用于其他适当材料。机舱结构中的螺栓和焊接接头设计也包括在内,以及铸造和锻造组件。规定了用于机舱结构设计过程的材料测试要求。虽然齿轮箱和主轴的结构连接在范围内,但齿轮和轴承的设计不包括在内。 根据本文件设计的风力涡轮机的安全水平应达到或超过IEC 61400-1:2019中固有的水平。提供了用于校准部分安全系数和设计过程的概率方法。 [外文原描述]: 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
