对二维颗粒环境中圆柱形物体的阻力进行了数值研究。结果表明，阻力定律可用屈服力和动力之和来拟合，动力可由简单碰撞模型来再现。径向应力对物体表面的角度依赖性由屈服力以下的高斯给出。研究了物体在屈服力以上的速度下降的概率，其中该概率与填充分数和拖曳力无关。
The drag of a cylindrical object in a two-dimensional granular environment is numerically studied. It is found that the drag law is fitted by the sum of the yield force and the dynamic force, the latter of which is reproduced by a simple collision model. The angular dependence of the radial stress on the surface of the object is given by the Gaussian below the yield force. The probability of the velocity drops of the object is investigated above the yield force, where this probability is independent of the packing fraction and the drag force.
