Thermostressed State of the Lock Joint of Turbine Rotor Blades of the First Stage of К-500-240 Steam Turbine Medium Pressure Cylinder

Thermostressed State of the Lock Joint of Turbine Rotor Blades of the First Stage of К-500-240 Steam Turbine Medium Pressure Cylinder

This paper investigates the temperature field effect on the stress state of the turbine rotor blade lock joint elements where breakdowns were observed. The turbine rotor blade joint, when heat is supplied from the steam flow, is in conditions of uneven heating. In this case, the physico-mechanical p...
