| Abstract: | A new seismic analysis method for large capacity fossil and nuclear steam turbines and its foundation is introduced.Comparing to normal calculation method in China,this method can represent a distribution of inertia forces,reaction forces and displacement at different time more accurately.By introducing these analysis options,building of the model,selection of the loads,a new solution for seismic analysis of fossil and nuclear steam turbines and its foundation with new configuration or large capacity is pre... |
