摘要
箱体晃动会使储液箱内液体的自由表面发生飞溅现象,而液体在储液箱内的飞溅会导致壁面受到高度局部冲击力,造成储液箱的结构损坏。为了研究储液箱内自由液面晃动规律,避免储液箱内液体晃动带来的风险,搭建了液体晃动模拟实验平台,模拟挡板固度比和储液箱内自由液面高度对储液箱内液体晃动的影响。结果表明:挡板固度比增大、储液箱内自由液面高度降低可以显著降低由于储液箱内液体自由表面的飞溅产生的壁面局部压力。研究结果为储液箱的结构设计和优化提供理论依据。
Sloshing will make the free surface of the liquid in the tank splash phenomenon,and the liquid splash in the tank will lead to a high local impact force on the wall,resulting in the structure of the tank damage.To study the sloshing law of free liquid surface in a liquid tank and avoid the risk caused by liquid sloshing in the liquid tank,a platform was built to simulate liquid sloshing and a 3D liquid tank model and used experimental methods to simulate the influence of baffle solidness ratio and free liquid level height on liquid sloshing in a liquid tank.After research and analysis,the conclusions are as follows:with the increase of the solid ratio of the baffle and the decrease of the height of the free liquid surface in the liquid chamber,it can significantly reduce the local wall pressure caused by the splash of the free liquid surface in the liquid chamber.The research results provide a theoretical basis for the structural design and optimization of the liquid storage tank.
