摘要

风荷载作用下柔性储液结构的动态响应属于典型的非线性流固耦合问题。采用多物质ALE有限元法，建立了大型柔性储液结构的有限元模型，数值模拟风荷载作用下柔性储液结构的动态响应，比较了不同风速对柔性结构的影响。仿真结果表明：风速越大，结构的最大主应力、质心偏移量也越大，当风速达到一定时，结构将会沿地面产生滑动。仿真结果为风荷载作用下柔性储液结构的抗风性研究提供参考依据。

Abstract

Dynamic characteristics of flexible container under wind load is typical problem about fluid-structure interaction under multiphase flow. Mutil-material ALE method is used to build the finite element model of the flexible container and wind. Dynamic characteristics of this structure under the different velocities of wind are compared. Numerical tests show that the the maximum principal stress and the deviation of the mass center become greater with respect to the increasing wind velocity untill the velocity achieves some certain value and the structure starts to slide on the ground, which provide important references for the research on wind-inducing response of flexible container.
