    Abstract
  • Taking the given fifth disc-blade structures of the gas turbine as an investigation object in consideration of the complex loads, the transient thermo-elastic-plastic finite element analysis of the contact disc-blade structures was completed using ANSYS program designed with ANSYS parameter design language(APDL). The stress and strain of turbine disc-blade structures were calculated respectively under the urgent loads and the typical loads. The disc-blade gap was regarded as a parameter, and the changes of stress and strain of the structures with different contact gaps were analyzed. Meanwhile, the exact value of the contact gap when the stress and strain changed suddenly was obtained. Moreover, the influence of the contact heat transfer coefficient on the stress and strain was discussed. Finally, some constructive suggestions were given for the processing of designing, machining, the improvement of material properties of the disc-blade structures and the operation and management of the gas turbine.
