Strong Earthquake Response Simulator

The strong motion response experiment device consists of the following: A 3D 6-axis vibration table system that can simultaneously or independently vibrate two horizontal axes (X Y axis), vertical (Z axis) vibrations, and rotational motion around each axis (θx, θy, θz), a long-period vibration experiment system that is placed on the vibration table system and is vibrated in conjunction with each other, devices that control them individually or simultaneously, coupled response control devices that link them simultaneously, and an overhead traveling crane.
The vibration table system is a device that accurately reproduces the response when strong earthquake motion acts on a complex structural system. It is possible to conduct strong motion response experiments on the entire structure system using a scaled-down model and vibration experiments on structures and substructures using full-scale models. In particular, this simulator can handle not only acceleration but also strong motion with large velocity. The maximum velocity of continuous sinusoidal excitation in each axis is ±50 cm/s. By using accumulators, it can reproduce the full-scale waveform of the 1995 Southern Hyogo Prefecture Earthquake observed at the Kobe Marine Observatory (maximum acceleration: horizontal 818 cm/s/s, vertical 332 cm/s/s, maximum velocity: horizontal 90 cm/s/s, vertical 40 cm/s), by simultaneous 3-axis (X, Y, Z) excitation. In addition, it has become possible to use it in conjunction with a long-period vibration experiment system, to establish technology for long-period and large-amplitude inputs.
The long-period vibration experiment system enables long-period, large-amplitude excitation of up to ±1.3 m, which was previously impossible and is particularly suitable for experiments on long-period earthquake motion countermeasures.
