Study of two-section composite chain of beads under vertical vibration

We investigated the dynamic properties of a two-section composite chain of beads under vertical vibration. By analyzing the chain’s motion, including phase-shift, mean dilation, center-of-mass displacement, and energy, we found that with different bead arrangements, the chain behaved in different wa...

Description
Summary:We investigated the dynamic properties of a two-section composite chain of beads under vertical vibration. By analyzing the chain’s motion, including phase-shift, mean dilation, center-of-mass displacement, and energy, we found that with different bead arrangements, the chain behaved in different ways. We believe that interaction existing at the interface between bead sections provides the underlying cause. This interaction causes different energy in different arrangements, which leads to different dynamic characteristics.
