G1000-2-2 円錐型容器内における粒状体の排出挙動に関する一検討(機械力学・計測制御部門一般講演(2):振動,社会変革を技術で廻す機械工学)
詳細
In this paper, we study the ejection behaviors of granular bodies in a circular cone shaped vessel. Here, elasto-plastic materials such as lead are treated. The elasto-plastic behavior at the impact is modeled as a bilinear type force-displacement characteristics, And we analyzed the behavior of each particle by Discrete Element Method (DEM). We conducted simple impact experiment and a corresponding analysis. Comparing the experimental and analytical result, we investigated the validity of a bilinear type force-displacement modeling. In numerical analysis, we investigated the ejection time and stoppage for various parameters such as the initial location, the taper angle and the friction coefficient. which have huge influence on the behavior of granular bodies.
