| Abstract: | This article describes a finite element model for the main shaft of one kind of bulb tubular turbine-generator, it are analyzed with NASTRAN on the basis of the static strength and the reasons of Vibration of main shaft. By analysis, it is known that the main shaft meets the requirement under various static loads and the possibility that main shaft occurs resonance is very small in the normal working conditions. The reliability and the product designing level are improved. |
