摘要
支臂作为弧形闸门传力的主导构件,其稳定性往往成为控制闸门安全的主要因素之一。在材料线弹性范围内,利用ANSYS软件对弧形闸门的等效空间构架模型进行了基于有限元法的特征值屈曲分析。探讨了影响支臂稳定性的因素,在实际工程中为提高支臂抵抗屈曲的能力避免其失稳具有一定的参考价值。计算结果表明支臂的截面特性、上下主框架载荷分配方式以及支臂的偏斜角度对支臂的屈曲荷载及屈曲模态均有不同程度地影响。
As the leading force transmission component of radial gate,the stability of the arm always becomes one of the main factors to control the safety.Within the linear elastic range of the material,the eigenvalue buckling analysis of an equivalent space model for a radial gate is processed based on the finite element method in ANSYS software.The factors affecting the stability of the arm is discussed,which has certain reference value in practical engineering to improve the ability of the arm to resist buckling and avoid its instability.The calculation results show that the cross-section characteristics,the load distribution mode and the deflection angle of the arm have different degrees of influence on the buckling load and mode of the arm.
