储液罐子结构数值仿真分析
|
摘要
由于有限元仿真需要假设材料性能,难以真实全面的反映储液罐的地震响应;而振动台试验只能完成较小比例的模型试验,与储罐原型差距很大。为此,提出了储液罐子结构振动台试验方法。采用Malhotra力学模型,将储液罐划分为试验子结构(罐底和土体)和数值子结构(储罐和液体)两部分。试验子结构放在地震模拟振动台上进行试验研究,数值子结构部分由计算机进行模拟。仿真计算表明:储液罐子结构仿真结果与全结构的非常吻合,仿真计算的储罐基底剪力与规范算法接近。
Due to the finite element simulation assume that the material properties,difficult to truly comprehensive the seismic response of the liquid storage tanks is reflected.And the shaking table test can only complete a small scale model test,a large gap with the tank prototype.To this end,a method of the liquid storage tanks substructure shaking table test is proposed,used the Malhotra simplified model,the liquid storage tank is divided into the experimental substructure(the bottom of the tank and soil) and the numerical sub-structures(storage tanks and liquid) in two parts.The experimental substructure on earthquake simulation shaking table test,the numerical substructure in part by computer simulation are put out.Simulation results show that: liquid tank sub-structure simulation results are in good agreement with the whole structure and the tank base shear simulation is close with the specification algorithm.
