摘要/Abstract

摘要： 建立了水流诱发长跨平板闸门顺水流方向弯曲振动自激响应的数学模型,通过试验确定了振动方程中的参数,达到可预报闸门振动的目的。计算值与实验值吻合,说明本文建立的数学模型基本上反映了平板闸门顺水流方向弯曲振动自激响应的内在机理。

Abstract: The differential equation of long span plate of flexual vibration is established in this paper.The parameters in the equation are determined by the model experiment.The calculation results indicate that the mathematical model can accordingly represent the intrinsic mechanism of the self excited vibration.It is useful for determining the characteristics of long-span plate gate vibration of an engineering structure.

Key words: long-span plate gate, nonlinear oscillator, steady self-excited response
