摘要
基于空间有限单元法,对闸门吊点施加1对单位力计算出2个吊点的相对位移———闸门扭转挠度系数,进而推算出闸门抗扭刚度系数和单位位移下的应力状态,据此最终解决弧门的扭转问题.并通过某一工程实例的分析计算,表明该方法在生产设计中具有较好的实用性,可以有效地解决弧形闸门的扭转计算问题.
By applying one couple of unit force on two suspension centers based on 3D FEM to calculate their relative displacement, coefficient of torsion displacement, the radial gate's torsional rigidity coefficient is derived; and its stress distribution is analyzed to solve radial gate's torsion problem. Furthermore, by calculating and analyzing the torsion problem existed in an actual radial gate, the method of unit force is proved to be scientific and practical, it can be used to deal with radial gate's torsion problem efficiently.
