摘要:

A simple and inexpensive mechanical model for the demonstration of chaos in a nonlinear deterministic system is described. Periodic, period‐doubled, and chaotic motions are exhibited by the model in agreement with the solutions of its governing differential equation. The model is sufficiently free from long‐term drifts to enable experimental Poincaré plots to be easily constructed. Such a simple mechanical model is shown to be ideal for use as a lecture room demonstration, as well as for a student laboratory.
