Using water-floating 3D-printed models, we investigated the dynamics of camphor boats, which are composed of a one-holed board and a camphor grain, under constraint conditions where a rod hooks the camphor boat on the water surface. When a camphor boat was connected to a water-floating disk or another camphor boat through a rod, we found that regular dynamics of the camphor boat appear and depend on the mobility restriction of the disk, the rod length, and the position of a slit of the camphor boat. We performed numerical simulations to reproduce the observed motions with theoretical models including constraint conditions.

使用水浮3D打印模型构造基于樟脑粒的化学机动式车架组件

使用水上漂浮的3D打印模型，我们研究了在一根杆将樟脑船钩在水面上的约束条件下，由单孔板和樟脑颗粒组成的樟脑船的动力学。当将樟脑船通过一根杆连接到水浮盘或另一根樟脑船上时，我们发现樟脑船出现规律的动力，并且取决于盘的活动性限制，杆的长度和狭缝的位置樟脑船。我们进行了数值模拟，以使用包括约束条件在内的理论模型重现观察到的运动。
