| Abstract: | Foundation type choosing of steam turbine-generator set foundation is one primary problem of large-sized steam turbine-generator set foundation design.Dynamics models are established in this study with beam element to analyze the sensitivity of the dynamic characteristic of largesized steam turbine-generator set foundation,and the sensitivity of different factors is gained.Based on the sensitivity analysis,the excellent scheme of one large-sized steam turbine-generator set foundation at home is gained.Compared with the results of model test,the veracity and feasibility of FEM numerical experimentation are validated.The methods can be used for optimum design of structure complicated and large-sized steam turbine-generator set system. |
