The mobile shaking table named BURURU is developed for the use of teaching dynamics in classroom. The shaking table and many kinds of experiment models are packed in a suitcase. The weight of case is about 10kg. BURURU uses the mechanism to transform the rotational movement to translational movement. The table vibrates harmonically when rotating the handle in front of the case. The prepared experimental models are the lumped mass model, two story frame structure where the roof, walls and braces are easily put on and taken off, the base isolation system, the tuned mass and liquid damper, the friction damper, the soft soil model and the liquefaction soil model. The students easily understand the dynamic phenomena of structure and soil through the combination of formulation, graph, animation of simulation analysis and the experiments using BURURU.
