| Abstract: | Design of a foundation of 660 MW turbo-generator manufactured by Shanghai Turbine-Generator Factory with import technology of Siemens and Westinghouse is described.The cross frame of the foundation was shortened to optimization as for the first time the domestic foundation of Siemens-model turbo-generator adopted.Dynamical analysis of the foundation was proceeded using finite element software such as ANSYS and MFSAP,and were compared with the 1∶10 physical model test.The results show that the all performance indexes of structure of the foundation satisfy the present code requirements;and they can be used as a design reference for similar projects. |
| Keywords: | turbo-generator foundation optimum design dynamical properties model test |
