| Abstract: | The full-scale mock-up of a kind of steam turbine blade was built. The vibration characteristics of the steam turbine blade were studied, the natural frequency of the turbine blade was calculated based on ANSYS structure analysis block. The frequency and shape of the blade vibration of the six orders were obtained. The analysis result can be used as reference for optimization design and vibration safeness verification for this steam turbine blade. |
