An experiment is described using double and triple conical pendulums to simulate the behaviour of a rotating chain. The first few rotation modes are calculated theoretically and provide good agreement with experimental results. By contrast, a chain containing many links is difficult to analyse, even though the first few nonlinear modes of a vertically suspended chain are easy to excite and are easily observed using a video camera. The experiment would be suitable as a student project since it is easy to set up and the physics is easily understood, unlike a conventional double pendulum.

旋转链的圆锥摆模型
描述了使用双锥和三锥摆模拟旋转链行为的实验。前几个旋转模式是从理论上计算出来的,并且与实验结果非常吻合。相比之下,包含许多链接的链很难分析,即使垂直悬挂链的前几个非线性模式很容易激发并且很容易用摄像机观察到。该实验适合作为学生项目,因为它易于设置且物理易于理解,与传统的双摆不同。
