Embodiment Construction
[0017] The technical solution of the vibration reliability design method of the turbine blade disc structure of the present invention will be further explained in conjunction with the accompanying drawings.
[0018] Considering the dispersibility of factors such as load, material and geometry, combined with the vibration reliability criterion of the turbine blade disc structure, the turbine blade disc structure vibration reliability design method provided by the present invention, the flow is shown in figure 2 .
[0019] (1) Initial plan design: first carry out the initial plan design, determine the preliminary structure according to the requirements of strength and aerodynamics, and make the resonance speed not fall near the engine design working speed or the engine stays at the resonance speed for a short time; calculate and determine The weight of the initial plan provides the initial weight for subsequent steps.
[0020] (2) Deterministic detailed design: Obtain the material pro...
