Abstract:
      A direction model of displacement response was established by the Fourier analysis to measured data. And based on the genetic algorithm, the parameter identification procedure put forward in the time domain was applied to study the vibration parameters identification of displacement reponse of the hydraulic turbine. The computational results indicate that the procedure has better stability and ability to resist measurement noises, and better identification precision, by which the satisfied vibration model can be set up. Furthermore, the post steps, such as the loading identification, optimum structure and prediction of damping of vibration effect etc., can be implemented reliably.
