Study of stress - strain state bandage rotor blades of steam turbines
The results of research to ensure the strength and operational reliability of some of the most intense and important elements of the blading - tselnofrezerovannyh bandages rotor blades of steam turbines designed to reduce vibrations of rotor blades. Analysis of stress - strain state tselnofrezerovannogo bandage within the elastic deformation using ANSYS software system based on the finite element method. The zones, which represent the greatest danger in the operation due to the power and the geometric stress concentration, the possibilities of reducing the local stresses. The results can be used in the turbine building, the design and operation of steam turbines. It is proposed to apply the results to prevent damage in the areas of stress concentration.
