Abstract
Based on the hydrodynamics, the air exciting-vibration force acting on the twist blade of steam turbine caused by clearance is studied by using the momentum theorem in this paper. Under considering of the design parameters of blade and the changing characters of inlet angle and outlet angle, the computational formulas are educed. It has solved the problem that Alford formulation is unsuitable to be used calculating the air exciting-vibration force acting on the twist blade because Alford formulation does not consider the design parameters of blade and the changing characters of inlet angle and outlet angle.
