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.

阐明了实际用途的动态稳定性，并检查了确定自激发稳定振动的非线性效应。首先，为了确定动态稳定性/不稳定性，在日本进行了使用钢rod折断激发方法的场振动测试。其次，模型门的实验室研究表明，当受到“摩擦维护稳定振动的稳定振动”的门暴露于超过阈值的初始位移时，可能会容易失败。此外，根据模型测试结果和现场振动测试结果尝试了自激发稳定振动的理论分析。
