Development of Teaching Material for Vibration Behavior

A Simple Model of a Playground Swing

Abstract

In learning the issue of vibration, it is important to know the essence of the various problems in resonance, natural frequency, natural vibration mode, and so on. However, it is really very hard to understand these phenomena. So, we started to develop the experimental equipment for the purpose of observing the vibration of mechanical systems. In this study, we developed a simple model of a playground swing with 2 degrees of freedom for teaching material. This swing is a compact folding type, so it's convenient to carry. In order to clarify how to use this swing, we simulated in eight patterns by using the software called DSS. As a result, the best way to swing this device was suggested.
