巨型浮体闸门的非线性振荡

Nonlinear oscillation of a large floating gate

  • 摘要: 在模型试验时,发现巨型浮体闸门在非线性约束下有大幅度的谐和振荡。根据浮体闸门的构造特征,建立了单自由度非线性振荡模型。由于闸门的自振周期是水位与垂直开度的函数,非线性约束对自振周期的影响也将是水位与开度的函数。还分析了不同开度情况下非线性约束对自振周期和振幅的影响。

     

    Abstract: Under the nonlinear binding forces the oscillations of a large floating gate are discussed. The harmonious oscillations with large amplitudes on the gate are discovered in the scale model.According to the structural feature of the floating gate, a nonlinear single - degree of harmonic oscillating model is set up. Due to the free vibration period of the gate is a function of the water level and gate opening, the,effect of the nonlinear binding forces is also a function of the same factors. The effect of nonlinear binding force on period and amplitude are also analyzed.
