Abstract
The temperature field and stress field of the twin-web turbine were studied based on the ANSYS. Through dividing different parts of the turbine disk into different heat transfer model,the temperature field distribution was accurately calculated.And then the stress field distribution of the twin-web turbine disk was calculated by using the method of the indirect heat-structure coupling. The results showed that the maximum average radial stress, the maximum average circumferential stress and the average circumferential stress of plate heart were 702.35 MPa, 679.68 MPa and 880.98 MPa,respectively.It not only met the requirement of the safety sactor, but also was less than the value of the yield strength,1 070 MPa. So the structure completely met the requirements of strength, and had the large development potential.
