储液容器三维流固耦合模态分析
|
摘要
本文采用强耦合法对储液容器流固耦合系统进行模态分析,并与附加质量法及文献计算结果相比较;分析储液深度变化对结构频率的影响,得到系统频率与水深关系曲线;进而考察提高结构刚度对系统频率的影响,得出容器刚度越大,流体对容器的影响越小的结论。这些将为圆柱形消化池及水池的动力分析提供参考。
This paper applies strong-interaction method to analyze the coupled modes of a fluid-filled container system.Then its results are compared with the results of added-mass method and literature.By changing the depth of the fluid,a curve which describes the relation between system frequencies and depth of the fluid can be found.Further-more by enhancing the stiffness of the structure,it can be found that the effect of the fluid onto the container will be smaller.The aboves will offer references for the dynamic analysis of the cylindrical digester as well as water tank.
