粘性滑塌颗粒的运动是一个非常复杂的问题。通过PFC 3D获得了实验装置无法捕捉的粘性颗粒的运动参数，分析了粘性阻尼系数对粘性颗粒运动的影响，包括特殊颗粒的峰值平移速度、峰值旋转速率和最大撞击力。当粘滞阻尼系数为0.3时，上述三个参数都有最大值，当粘滞阻尼系数为0.5时，上述三个参数都减小。较小的颗粒比较大的颗粒更容易受到粘性阻尼系数的影响。
It is very complex that the viscous slump particle motion. The obtained motion parameters of the viscous particles which can’t be captured by experimental facility through PFC3D, which are used to analysis the influence of the viscosity damp coefficient to the motion of it. The influence includes the peak translation velocity, peak rate of rotation of the special particle and the biggest impact force. All of which have the maximum value when the viscosity damp coefficient is 0.3, but all of which reduce when the viscosity damp coefficient is 0.5. The smaller particle is easy to suffer to the influence of the viscosity damp coefficient than the bigger particle.
