摘　　要：假定料仓内散体是服从Mohr-Coulomb屈服准则的理想弹塑性介质[1],散体与仓壁之间的摩擦属于Coulomb摩擦接触问题。通过ABAQUS有限元软件对料仓在静载作用下进行应力分析,将有限元分析的结果与实际测试结果相校核,在此基础上得到料仓的力学性能,进而优化设计。It is assumed that granular material in the silo is subject to Mohr-Coulomb yield criterion ideal elastic- plastic medimn, the friction between granular material and warehouse wall belongs to the Coulomb friction contact problem. ABAQUS finite element software is used to carry out stress analysis of silo under static load. The result of finite element analysis is compared with the actual test results. The mechanical properties of the silo is obtained for optimal design.
