  • The effects of temperature distribution on stress level in a rotating disk at a fixed flux of cooling air was numerically studied using coupled thermal-elastic method based on the finite element technique.The rotating speed is fixed at 6000 r/min,and the temperatures of inner rim and outer rim are 600 ℃ and 650 ℃,respectively.Detailed information of stress level change with surface temperature distribution of rotating disk was discussed.Numerical results reveal that there exists a strong relation between the surface temperature distribution of rotating disk and stress level inside the rotating disk.The V-shape temperature distribution can significantly reduce the stress level.
