Sensitivity Analysis of 1000MW USC Units Shafting Torsional Vibration Based on ANSYS

摘要：

　　To calculate a shafiings natural frequency of torsional vibration is one of the most important tasks in turbo-generators design, manufacture and frequency adjusting process.The sensitivity analysis of shafting structural parameters impact on the torsional vibration characteristics has important significance in reducing the amplitude of torsional vibration and ensuring the turbo-generators safe operation.In this paper, a 1000MW USC unit was taken as a research object to analyze the shaftings sensitivity to moment of inertia.
