2-axis Vibration Test Systems
The 2-axis Vibration Test Systems have G-8-2 Series; 2-axis (1-axis each of horizontal and vertical) simultaneous excitation possible and G-8-1 Series; 2-axis sequential (one axis by one axis) excitation possible, suited most to transportation tests for large, heavy specimens eliminating troublesome labor as no vertical & horizontal tables handling and also no specimen unloading & loading which is a MUST with the conventional Single-axis Vibration Test Systems. In addition to the 8-axis Vibration Test Systems in our Catalog, there are 2-axis Vibration Test Systems with larger displacement and larger force also available. Please contact us for more information if needed.

Minimalizing
‘cross-talks (unnecessary vibration)’
Long-experienced technology for the unique Hydrostatic Bearing Coupling Technique allows for restraint on ‘cross-talks’ among the two axes, thus making it easy to control in accordance with the set 2-axis vibration test conditions.
