针对底铰式钢闸门底横轴受力情况复杂、设计计算过程繁琐等问题,在分析、建立底横轴截面尺寸计算模型的基础上,对底横轴主要截面尺寸外径的影响因子进行敏感性分析及曲线拟合,确定了与底横轴外径呈线性正相关的影响因子,并予以修正,得出了外径随影响因子变化的曲线拟合公式,较大程度地简化了底横轴设计的计算过程,并根据工程的实际情况对拟合公式进行了验证,证明了拟合公式的可靠性和在实践中利用拟合公式进行设计的可行性.
Aiming at the problems that the horizontal axis of the bottom hinged steel gate bottom is complex and the calculation process is complicated, the influencing factors of the outer diameter of the main section of the bottom transverse axis are analyzed based on the analysis of the calculation model of the bottom transverse axis section size Linear analysis and curve fitting, the influencing factors that are linearly and positively correlated with the OD of the bottom horizontal axis are determined and corrected, and the curve fitting formula of the outer diameter changing with the influencing factor is obtained, which simplifies the bottom horizontal Axis design calculation process, and according to the actual situation of the project to verify the fitting formula to prove the reliability of the fitting formula and in practice the feasibility of using the fitting formula design.
