仓内散粒体压力分布规律的研究

Analysis of the Stress Distribution of Granular Materials Flowing in Converging Hopper Sections

本文对仓内散粒体做稳定、整体、卸载流动时的理想刚塑性模型用分离变量的级数展开法对其进行了数值计算，纠正了原结论性公式中的错误［１］，扩充了计算公式的范围，并且，给出了应力沿径向的分布规律。

In this paper,the ideal rigid一plastic model of the granular materialsflowing in converging hopper sections is computed numerically with the series expandingof the separating changeable quantity(The flow is seeady,mass and passive).The errorsof the formulas are corrected.The boundarys of the computing formulas are enlargedand the distributing laws of the stress along the direction of the radius are also provid-ed.
