混凝土反射临界装置的外容器内充装大量混凝土作为反射层,为分析其在实验期间装置能否承受得住混凝土的重压而不至于破坏,以及容器底板是否会出现过大的下沉位移,使用ANSYS对该装置进行了静力计算。有限元模型主要采用三维壳单元SHELL93,混凝土的重压按等效重量施加 In order to analyze whether the device can withstand the weight of concrete during the experiment without damaging and whether there is excessive sinking displacement of the container base plate, a large amount of concrete is filled in the outer container of the concrete reflection critical device as a reflection layer, The device was statically calculated using ANSYS. The finite element model mainly uses the three-dimensional shell element SHELL93, the concrete weight is applied according to the equivalent weight
