The Modern Single Shaft Gas Turbine Rotor Stress-Strain State Determination Taking into Account the Contact Thermoelasticity Problem
Abstract:The paper outlines a finite elements refined mathematical model of the stress-strain state of single shaft gas turbine engine that can be used in ground or floating power plants. The mathematical model, built on the basis of special contact finite elements takes into consideration the contact thermoelasticity problem in the joint area of disk and blades. On the basis of the developed mathematical model the fields of turbine rotor dynamic stresses and displacement have been found too. To make the clear decision… Show more
