【摘要】：分别采用弹簧质量模型和流固耦合模型2种方式对大型储水罐进行相互验证计算。弹簧质量模型基于HOUSNER理论,计算出脉冲液体质量M0、脉冲液体重心高度H0、对流液体质量M1、对流液体重心高度H1以及弹簧模拟对流液体晃动频率的等效刚度k1,并以此作为有限元模型的输入参数;流固耦合模型采用ANSYS的流体单元fluid80模拟液体,壳单元shell181模拟储水罐,考虑液体及结构阻尼,计算结构在地震时程下的响应。
[Abstract]:Spring mass model and fluid-solid coupling model were used to verify and calculate the large water storage tank. Based on HOUSNER theory, the spring mass model is used to calculate the equivalent stiffness k _ 1 of pulse liquid mass M _ 0, pulse liquid gravity center height H _ 0, convective liquid mass M _ 1, convective liquid gravity center height H _ 1 and spring simulating convective liquid sloshing frequency. It is used as the input parameter of the finite element model. In the fluid-solid coupling model, the fluid element fluid80 of ANSYS is used to simulate the liquid, and the shell element shell181 is used to simulate the water storage tank. Considering the damping of the liquid and the structure, the response of the structure under the earthquake time history is calculated.
