浅谈汽轮机基础动力分析

Dynamic Analysis of the Steam Turbine Foundation

论文以海南金海浆纸业有限公司热电厂三期扩建工程的B90-12.3/1.6型汽轮机(哈尔滨哈汽实业开发总公司制造)为例,采用MIDAS GEN系统对汽轮机基础进行动力分析,得出汽机岛基础在汽轮机各种频率运行时的线位移,并将不同柱截面的汽轮机基础在同种工况下的线位移进行对比,可为以后的同类工程提供参考。

Taking the B90-12.3/1.6 steam turbine(manufactured by Harbin Haqi Industrial Development Corporation)of the third phase expansion project of thermal power plant of Hainan Jinhai Pulp&Paper Company Limited as an example,this paper uses MIDAS GEN system to analyze the dynamic characteristics of the steam turbine foundation,and obtains the linear displacement of the turbine island foundation at various frequencies in the steam turbine operation.The comparison of the linear displacement of the cross-section steam turbine foundation under the same working conditions can provide a reference for similar projects in the future.
