论文摘要
我们研究了六角形棱镜的动力学如何在摩擦和结构不对称的情况下在地板变化上滚动。结果表明，不对称性诱导非对逆局动力学，其中棱镜仅在一个方向上滚动，而不论初始速度的方向如何。虽然这种行为主要被摩擦的增加抑制，但我们观察到存在一定范围的摩擦系数，而在非恢复了非重生。这表明摩擦不仅减少了动力学，而且通过向棱镜施加扭矩来帮助它。
We investigate how the dynamics of a hexagonal prism rolling on a floor change with friction and structural asymmetry. It is shown that the asymmetry induces the non-reciprocal dynamics where the prism rolls only in one direction regardless of the direction of the initial velocity. While such behavior is primarily suppressed with increasing friction, we observe that there is a certain range of friction coefficient where the non-reciprocity is restored. This suggests that the friction not only diminishes the dynamics, but also assists it by exerting a torque to the prism.
