摘　　要：在总结汽轮机基础设计常用规范的基础上,结合典型600MW汽轮发电机基础动力特性试验的结果,分别以动力机器基础规范和ISO标准对控制点的振动进行评价,并对规范的严格程度进行分析,为进一步对比和评价各规范奠定了基础.The results of vibration testing of three typical foundations of turbogenerator are analyzed.The comparison of two standards GB50040-96(to evaluate the foundation through linear displacement of the disturbing force points on the foundation of turbogenerator and ISO10816-2(to evaluate the foundation through RMS velocity of the bearing brackets of turbogenerator is also made.Lots of analysis of experiment data are made to search the relationship between vibration of bearing brackets and vibration of foundations.The safety coefficients of the chosen foundations using GB50040-96and ISO10816-2are also given.It is hoped that the results will be for reference in design and judgement of foundations of turbogenerator.
