| Abstract: | Dynamical properties of a turbo-generator foundation impose much effect on safe operation of a power plant. At first,dynamic and sensitive functions of foundation were set up separately; optimization theory and process were proposed then. At last, a 1 000 MW turbo-generation foundation was optimized.Analytical results show that the optimal case can reduce both concrete usage and forced vibration amplitude. |
