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 the previous study, it was reported on our horizontal shaking table. In this study, the vertical shaking table was made successively. Then an experimental equipment for vehicle vibration of bouncing and pitching was developed. By using this apparatus, we clearly observed the primary and secondary resonances and natural vibration modes.
