【Abstract】 Based on the hydro--dynamics,computing formulas of air-exciting-vibration are presented for the straight, short twist and long twist blades and the control stages of the steam turbine in the uniform and non-uniform air-flow fields. Furthermore introduced are computing program designing for the air-exciting-vibration force and methods for the intepration in the formulas.\;更多还原
