摘　　要：高转速汽轮发电机以提高发电功率、提升经济效益的优势,在火力发电厂中的应用越来越广泛。而目前国内对转速高于3000 r/min汽机机组的基础动力分析的研究及设计标准相对较少。以某工程的高转速汽轮发电机基础设计方案为背景,采用有限元分析软件SAP2000对汽机基础进行模拟,分析其在机器运行轴承振动影响下的动力响应。对比国内最新现行规范、德国《动力设备基础设计标准》(DIN4024)和美国《大型汽机发电机基座设计导则》ASCE标准,讨论高转速汽轮发电机动力分析中的动参数取值及评价标准,对同类工程设计有一定参考价值。The high speed steam turbine generators are used in various types of power generation projects to improve generating efficiency and economic benefit.At present,the domestic research and design standard of the high speed(≥3000 r/min)steam turbine-generator foundation dynamic analysis are relatively insufficient.Base on the design project of high speed steam turbine generator foundation,the finite element model is developed by using SAP2000 and the dynamic response is analyzed at the operating frequency.This paper compares the latest domestic standard with German DIN4024 standard,America ASCE standard to discuss the dynamic parameter and evaluation criteria.The conclusion has a guiding significance for the future steam turbine generator foundation design and research.
