N2 - Contact stress analysis and optimization design of single crystal turbine blade tenon/disk mortise structure considering thermal-solid coupling is proposed in this paper. Contact thermal conductivity analysis of turbine blade/disk mortise structure is carried out to obtain temperature distribution. Contact stress of mortise structure considering temperature influence is analyzed by FEM method. On basis of contact stress analysis, the optimization design method considering thermal-solid coupling is proposed. Broaching angle, wedge angle and gap distance are chosen as optimization design variables. The minimum Mises stress, average tensile stress and average compressive stress are chosen as optimization objectives. A three fir tree tenon/mortise structure is optimized to decrease the maximum Mises stress 14% by proposed method.
