Research Abstract |
Dynamic stability of the practical use Tainter gates were clarified, and the nonlinear effect which determines the self-excited steady vibration were examined. First, in order to identify the dynamic stability/instability, the field vibration test with steel-rod breaking excitation method were conducted to the practical use Tainter gates in Japan. Second, the laboratory studies of a model gate show that a gate with "friction-maintained steady vibration" can fail readily when exposed to an initial displacement exceeding a threshold value. Moreover, the theoretical analysis of self-excited steady vibration was tried based on the model test results and field vibration test results.
