摘要
采用基于离散单元法的颗粒流程序建立筒仓模型,通过对模型基础施加有规律简谐地震动,模拟了筒仓结构在简谐地震动作用下的仓壁侧压力变化情况、位移响应和速度响应,并且通过对筒仓内无散体颗粒、有一半散体颗粒和装满颗粒3种工况下筒仓的动力响应进行模拟,得出筒仓结构与散体颗粒相互作用的动力响应影响情况.
A silo model was established by particle flow code based on discrete element method. Regular harmonic seismic motion was applied on a model base, and the change of wall lateral pressure, the displacement response and the velocity response of the silo structure were simulated under harmonic seismic motion. The simulation of dynamic response of the silo was conducted under the condition of no granular materials, half-filled with the granular materials and fully - filled with the granular materials to obtain the influences of the interaction of the silo structure and the granular materials on the dynamic response of the silo structure.
