摘要
近年来,国内引进了多种大容量汽轮发电机组,同时国内设计院等相关单位也在参与国外工程的设计和建设。为此,有必要掌握国内外流行的大型汽轮发电机组基础设计标准中的动力分析方法。介绍了汽机基础结构分析用的4种计算模型,强迫振动分析的扰力取值和阻尼系数比,以及强迫振动控制标准,最后,概述了各种标准的动力分析方法。
Various large-scale turbine-generator units have been imported in China for recent years and domestic design institutes have participated foreign power projects.So it is necessary to master main dynamic analysis methods in both domestic and foreign turbine-generator foundation design standards.The paper describes 4 calculation models for turbine foundation analysis,disturbance force valuing and damping ratio,as well as forced vibration control standard.It also illustrates dynamic analysis method of both domestic and foreign standards briefly.
