弧面三角闸门的静力数值分析

基于大型有限元分析软件ANSYS,以夏仕港船闸弧面三角闸门的静力学分析为背景,建立起闸门的有限元模型。综合考虑重力、风载荷、水压力等主要载荷影响,对闸门在蓄水与通航条件下进行静力分析,得出不同工况下闸门的应力及变形分布情况,并对闸门强度、刚度和稳定性进行校核,评估出闸门的安全性。结果表明:船闸弧面三角闸门的整体以及各构件满足强度、刚度、稳定性要求,该研究为同类型水工钢闸门的设计与校核提供理论参考。

Numerical analysis on static force for cambered triangular gate

Based on large finite element analysis software ANSYS, took static analysis of the ship lock's cambered triangular gate of Xia Shi harbor as the background, the paper built the finite element model of gate. Considering the major load effects of gravity, wind-force, water pressure, it analyzed the static characteristics of gate in the condition of water storage and shipping,got the distribution situation of stress and deformation under different operations, checked the strength, rigidity and stability of the gate, and evaluated the safety of gate too. The results indicated that the whole arc triangular gate and every structure part meet the requirements of strength, rigidity and stability.The study can provide theory reference for the design and check of similar hydraulic steel gate.
