摘要

本文建立了带活动挡板的储罐内液体晃动的流固耦合力学模型。活动挡板通过弹簧和阻尼器与侧壁相连，只能沿底部储罐的宽度方向移动。采用有限元法（FEM）和有限体积法（FVM）建立模型。为了研究流体-挡板-油箱耦合系统的动力特性，进行了数值衰减试验和扫描试验，研究了不同耦合系统的模态频率和振型。结果表明，弹簧刚度在耦合系统中起着至关重要的作用，阻尼器可以增强罐内活动挡板的抗晃动效果。挡板的附加质量远远大于挡板本身的质量，是影响耦合系统模态频率和动力响应的主要因素。

Study on dynamic characteristics of coupled sloshing system with a movable baffle

A fluid-structure coupling mechanical model of liquid sloshing in the tank with the movable baffle is presented in this paper. The movable baffle is linked to the side walls by springs and dampers and can only move along the width direction of the tank in the bottom. The model is established using Finite Element Method (FEM) and Finite Volume Method (FVM). To investigate the dynamic characteristics of the coupled system of fluid-baffle-tank, the numerical decay tests and sweep tests are conducted, the modal frequencies and shapes of different coupled system are also studied. The results reveal that spring stiffness plays a crucial role in the coupled system and the damper can enhance the anti-sloshing effect of the movable baffle in the tank. The added mass of the baffle is much greater than the baffle mass, and it is the main factor affecting the modal frequencies and dynamic response of the coupled system.

期刊介绍： The Journal of Fluids and Structures serves as a focal point and a forum for the exchange of ideas, for the many kinds of specialists and practitioners concerned with fluid–structure interactions and the dynamics of systems related thereto, in any field. One of its aims is to foster the cross–fertilization of ideas, methods and techniques in the various disciplines involved. The journal publishes papers that present original and significant contributions on all aspects of the mechanical interactions between fluids and solids, regardless of scale.
