插入型组合式金属防洪挡板有限元仿真分析

Finite element simulation of plug-in combined metal flood protection baffles

基于大型有限元分析软件ABAQUS,对不同高度、不同插入深度的组合式金属防洪挡板在静水荷载、动水荷载及冲击荷载3种荷载组合作用下结构的力学性能进行分析。计算结果表明,该型号组合式金属防洪挡板在防水高度不超过3 m、插入深度为0.4 m时,系统的最大应力及最大挠度均满足安全要求,且防水高度大于1 m的情况下插入深度不应低于0.2 m。

Based on the large-scale finite element analysis software ABAQUS,the mechanical properties of the combined metal flood protection baffle with different heights and insertion depths under the combination of hydrostatic load,hydrodynamic load and impact load are analyzed.The calculation results show that when the waterproof height of this model of combined metal flood protection baffle does not exceed 3 m and the insertion depth is 0.4 m,the maximum stress and maximum deflection of the system meet the safety requirements,and the insertion depth should not be less than 0.2 m when the waterproof height is greater than 1 m.
