| Abstract: | Thermal field of turbine stator of a type of aeroengine was solved according to piecewise linear interpolating method and the result is used to acquire thermal-structural coupling feature of the turbine stator model and the 1 / 72 sector model.Vibration characteristics of this turbine stator and the thermal stress under working condition were obtained by structure modal analysis and stress calculation.Further analysis verified the rationality of the calculation results. |
