Development of Teaching Material for Motion and Vibration

Turning Motion of a Crane

Abstract

In learning the issue of motion and vibration of mechanical system, it is important, first, to establish the equation of motion, second, to know the essence of the various problems such as the natural frequency and the natural vibration mode, and so on. However, it is really very hard to understand these phenomena. For these reasons, the authors have developed the learning materials in this field. Specifically, they are the educational motion simulation software called DSS and the various experimental apparatuses for observing motion and vibration phenomena. In this research, as a complex system including both motion and vibration, we focused on the turning motion of a crane and developed an experimental apparatus. Moreover, we simulated the behavior of suspended load during turning motion with DSS, and compared experimental results with simulated ones.
