Abstract

In order to study the performance differences among struts of a heavy-duty gas turbine, three-dimension finite-element models of several struts were established by Pro/Engineer. Firstly, the stresses of three struts were obtained only considering the rotor gravity. The magnitudes and distributions of stress and influences of the width and thickness for support plates on stiffness are studied. The results show that radial struts 2 are superior to radial struts 1 and tangential struts is superior to radial struts. The sensitivity of stiffness to the width of support plates is greater than the thickness. Then, the distribution of temperature was obtained by the thermo-fluid-solid coupled method in CFD software to calculate the thermal stress of radial and tangential struts. The results show that although the magnitudes and distributions of temperature are similar, the thermal stress of tangential struts is smaller than that of radial struts.
