Abstract
Based on the hydro-dynamics, the computing formulas for air-exciting-vibration force are derived for straight blade, short twist blade, long twist blade and the control stage of steam turbine in uniform air-flow field. Using the presented formulas, the air-exciting-vibration force can be directly calculated based on the design parameters and air-flow parameters of steam turbine. The numerical tests show that the presented formulas are correct and reliable.
Keywords
