摘　　要：为了准确地计算贮料侧压力,探究在静态条件下钢筒仓仓壁的侧压力分布情况。利用ANSYS建立不同高径比的简易平底仓模型,模型中贮料的本构选用Drucker-Prager模型来模拟,通过接触单元模拟筒仓壁与贮料之间的摩擦接触。将数值模拟结果与我国的钢筒仓技术规范进行对比来验证有限元计算结果的准确性,分析结果显示,有限元结果基本符合规范中静态贮料侧压力的分布曲线。To calculate the side pressure of the silo accurately,the distribution of the side pressure on the wall of the steel silo under the static condition was studied.A simple flat bottom silo model with a different ratio of height to diameter was established by ANSYS.In the model,the Drucker-Prager model was used to simulate the constitutive structure of the stored granular materials,and the friction contact between the wall and the stored material was simulated by the contact unit.The numerical simulation results were compared with the technical code of steel silo in China to verify the accuracy of the results.The results indicate that the finite element results basically conform to the distribution curve of static stored material side pressure in the code.
