Various kinds of "Bururu"
Name	Photo	Operation	Features	Use
Hand-crank Bururu		The rotational movement given by revolving the hand crank is converted to parallel movement to vibrate the platform.	Compact in size, it can be put in an attache case for easy carrying. One can physucally feel the frequency characteristics by rotating the handle. Various models are put in the case.	It is availavle for a variety of uses, such as lectures and events. It provides a visual illustration of vibration phenomena, allowing students to effectively learn bthe principle of vibration.
Compact Vibrator Bururu		The built-in battery creates lateral vibration. The dial can change the frequencies of vibration.	It can be put on a small model to vibrate the building. It is effective in making people understand the resonance curve.	It is effective in explaining the principle of an excitation experiment often used in vibration experiments of buildings.
Electric Bururu		Driven by a built-in battery. The dial can change the vibration frequency to cause the platform to tremble.	Since vibration frequency is mechanically controlled, constant and reproducible vibration can be generated. Light in weight and easily transportable.	It can easily reproduce vibrations of continuously changing frequencies and vibrations of short and long frequencies that are difficult to reproduce by the handcrank version.
Vehicle Bururu		Moving the handle installed at the cargo carrying cart back and forth vibrates the cart.	As the device creates vibration with a model similar to an actual wooden building, one can feel the effect of earthquake-resistant reinforcement. It can also show distortion by eccentricity. Children can ride on the top to feel the vibration.	It helps people easily feel the effect of seismic reinforcement of a wooden structure.
Vehicle Bururu (2F)
Wooden Bururu		The truck is shaken by moving the steering wheel installed in a luggage vehicular truck back and forth.	It is possible to experiment by a model that is nearer an actual wooden building. It is possible to actually destroy. To which the continuous column breaks can be confirmed. It is easy to understand because the contrast experiment is done by arranging two houses.	The difference of strength in the building by the presence of reinforcement can be experienced very plainly.
Temple Bururu
Self-propelled Bururu		The built-in battery drives the servo motor to reproduce input seismic waveforms.	It reproduces long-term and longstroke seismic vibrations that cannot be reproduced by a conventional vibration platform. One can stand on the platform and feel the vibration.	If residents of or people related to high-rise buildings experience this simulator to feel a quake, their awareness of DPM will be effectively enhanced.
Pull rope Bururu
Paper Bururu		A house model assembled with pieces of paper is caused to laterally tremble by hand.	One can build this simulator with paper by themselves and feel the differences in natural frequency and the effectiveness of braces as they vibrate it.	When used at a participatory workshop, the paper simulator becomes a good souvenir for workshop participants. It is effective in making children take an interest in the vibration of buildings.
