摘要
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、动水荷载以及冲击荷载等荷载组合作用下的结构进行动力学有限元仿真。计算结果表明,该型号的组合式金属防洪防水高度不超过3 m的情况下插入深度为0.4 m时满足安全要求,且对不同挡水高度下的防洪结构进行模态分析,可为避免结构固有频率与环境荷载频率相互耦合提供科学指导。
Based on the large-scale finite element analysis software ABAQUS,the dynamic finite element simulation of the structure of the combined metal flood control baffle with different heights and different insertion depths under the combination of hydrostatic load,hydrodynamic load and impact load is carried out.The calculation results show that the combined metal flood control waterproof height of this model does not exceed 3m,and the insertion depth is 0.4m to meet the safety requirements.The modal analysis of the flood control structure under different water retaining heights can provide scientific guidance for avoiding the coupling between the natural frequency of the structure and the environmental load frequency.
