中美德汽机基础设计标准探讨

Discussion on the Steam Turbine-generator Foundation Design Standards of China, America and Germany

本文针对中国标准GB50040-96《动力机器基础设计规范》、德国标准DIN4024-1988《机器基础-支承带转动部件的机器的柔性结构》、美国标准《大型汽轮发电机基座设计导则》在汽轮发电机基础设计中的应用进行了对比分析。分别总结出三国标准在汽轮发电机计算中荷载分类、扰力取值、动力设计及限值要求等方面的区别,为汽轮发电机基础设计计算提供参考。

This paper has compared the application of turbine-generator foundation design standards between the Chinese standard GB50040-96 Code for Design of Dynamic Machine Foundation, German Standard DIN4024-1988 Machine Foundations Flexible Structures that Support Machines with Rotating Elements, and American Standard Design of Large Steam Turbine-generator Foundations. The differences of load classification, disturbance force, dynamic design and limit requirements in the design of turbine-generators foundation are summarized respectively, which provides reference for the design and calculation of turbine-generator foundation.
