Multi-Axis Vibration Test Systems / Shakers
SHINKEN succeeded in commercializing the world’s first Electro-Dynamic Multi-Axis Vibration Test System. Since then, SHINKEN has been enjoying the world top-class installation record of Multi-Axis Vibration Test Systems with accumulated knowledge and long years experience as well as its uniquely-designed Hydrostatic Bearing System which minimizes cross-talks among axes and also makes the Multi-Axis Vibration Generators compact. In addition to simultaneous excitation, Multi-Axis Vibration Test Systems have been used for the sequential test of each axis thus contributing to time saving and labor elimination as no troublesome vertical & horizontal tables handling and also no specimen unloading & loading are needed. 2-axis and 3-axis Vibration Test Systems are available.
Advantages of SHINKEN
Reduction of Test Time and Labor
With the 3-axis Sequential Vibration Test Systems, vibration directions can be changed with one-touch switch operation or automatic direction change setting thus contributing to time saving and labor elimination as no troublesome vertical & horizontal tables handling and also no specimen unloading & loading are needed. With the 3-axis Simultaneous Vibration Test Systems, 3-axis simultaneous excitation can be carried out thus eliminating the test time drastically to less than 1/3.
Simulation of Real World-Like Vibrations
With the 3-axis Sequential Vibration Test Systems, vibration directions can be changed with one-touch switch operation or automatic direction change setting thus contributing to time saving and labor elimination as no troublesome vertical & horizontal tables handling and also no specimen unloading & loading are needed. With the 3-axis Simultaneous Vibration Test Systems, 3-axis simultaneous excitation can be carried out thus eliminating the test time drastically to less than 1/3.
Minimizing "Cross-talks (Unnecessary Vibration)"
Long-experienced technology for the unique Multi-axis Hydrostatic Bearing Systems allows for restraint on "Cross-talks" among axes thus making it easy to well control in accordance with the set 3-axis vibration test conditions.
3-Axis Vibration Test Systems G-6 Series
Towards "More Realistic Vibration"
The G-6 Series Vibration Test Systems (VTSs) can create "More Realistic" vibration than any conventional Single-axis VTSs by exciting specimens in three directions; left & right(X), back & forth(Y) and up & down(Z), thus most suited to seismic simulation, transportation PSD simulation, actual vehicle running simulation etc.
Restraint on "Cross-talks" (Unnecessary Vibration)
Long-experienced technology for the unique Hydro-static Bearing systems allows for restraint on "Cross-talks" among the three axes, thus making it easy to control in accordance with the set 3-axis vibration test conditions.
3-axis Simultaneous VTSs & 3-axis Sequential VTSs Available
In addition to 3-axis Simultaneous VTSs, 3-axis Sequential VTSs, only capable of testing axis by axis with one-touch switch-over or optionally available automatic series tests (in order of Z→X→Y) are also available.

1. The upper frequency for sine is a frequency up to which the max. force output can be achieved, while that for random is a frequency up to which a PSD random pattern having a -6dB/oct or steeper roll-off over the upper frequency for sine(or lower) can be controlled. The lower frequencies for control and for excitation are 2Hz and 0.5Hz, respectively unless especially requested. 2. All the Power Amplifiers are of an air cooling type. 3. The HT and LT type systems having a max. force output of 3kN(306kgf), 7kN(714kgf) or 20kN(2,040kgf) are also available. 4. With the employment of the 1-ch Power Amplifiers instead of the 3-ch Power Amplifier, the 3-axis (Automatic) Sequential Vibration Test Systems are also available, which can be upgraded into the Triaxial Simultaneous Vibration Test Systems in the future by adding 2-ch Power Amplifiers and necessary controllers. 5. Vibration Generators with other table sizes than shown above are also available upon request. 6. Power required is 3-phase 200/220/380/415V, 50/60Hz. 7. For better acceleration distribution on the table, the movable weight will be heavier by 10 to 30kg for addition of proper balance weights. 8. For the G-6230 (30kN), air-cooled systems are available upon request. 9. For the air-cooled systems, it is recommended that the hot air from the cooling blower be sent to outside. 10. A System having a bigger force output and/or larger displacement than shown above is also available upon request.

2-Axis Vibration Test Systems G-8 Series
Easier Change of Vibration Directions with One-touch Switch Operation
G-8 Series can eliminate time-consuming work for the specimen handling and changing vibration directions with one-touch switch operation, thus most suited to tests for large and heavy specimen.
Space-saving
G-8 Series' 2-axis Vibration Generators(VGs) have a common table for both horizontal and vertical excitation, thus making the space needed for the VGs smaller than the conventional single-axis VGs which require two tables; especially VGs with large tables.
Cost-saving
As it is said that vertical and the so-called "Major Horizontal" excitation can precipitate over 90% of the hidden flaws, 2-axis simultaneous excitation can be a lower cost solution.
2-axis Simultaneous VTSs & 2-axis Sequential VTSs Available
In addition to 2-axis Simultaneous VTSs, 2-axis Sequential VTSs, only capable of testing axis by axis with one-touch switch-over or optionally available automatic series tests (in order of Z→X) are also available.
