Hydraulic Elastic Vibration Analysis of Hydraulic Turbine Blade

Abstract:

Article Preview

This paper analyses quantitatively mechanism that hydraulic turbine runner blade tail produces Carmen vortex column, and the blade hydraulic elastic vibration which is produced by Carmen vortex column, also analyses the harms of blade hydraulic resonance, puts forward corresponding preventative measures. For the stable operation of large Francis hydraulic turbine, these measures have reference meaning.
