摘要 文章用有限元法对筒仓进行了动态压力数值模拟,得到了沿仓壁和漏斗壁动态压力数据,并将模拟结果与测试数据、规范、Janssen公式和微力学离散元模拟结果进行了对比分析,表明有限元模拟结果与规范、Janssen公式、动态压力测试结果吻合良好,说明用有限元法模拟筒仓的静态压力和动态压力是可行的。 Numerical simulation of silo's dynamic pressure is carried out by the finite element method. The dynamic pressure distribution along the wall of silo and hopper is gotten and compared with the experiment data, the State code, the result by the Janssen formula and the simulated data of DEM. It is shown that simulated results of this paper are consistent with the data which are compared.
