2-axis Vibration Test Systems
Applications:
Haida's uniquely-designed Hydrostatic Bearing System minimizes cross-talks among all the axes and also makes the 2-axis Vibration Generators compact. The Systems are capable of 2-axis simultaneous excitation; horizontal (X) and vertical (Z), simulating 'More Real-world Vibration' as it is said that 2-axis excitation can precipitate over 90% of the hidden flaws detectable. In addition to simultaneous excitation, 2-axis Vibration Test Systems have been used for sequential tests of 2 axes thus contributing to time saving and troublesome labor elimination as no vertical & horizontal tables handling and also no specimen unloading & loading are needed, especially employed for transportation tests for large, heavy specimens.

Test standards: MIL-STD, DIN, ISO, ASTM, IEC, ISTA, GB, GJB, JIB, BS, etc.
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 2-ch Power Amplifier, the 2-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 1-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-8230 (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.

OVER-THE-ROAD TRAILER SIMULATION
The following breakpoints are for an Over-the-Road trailer typical for parcel delivery movement and shall be programmed into the vibration controller to produce the acceleration yersus frequency profile (spectrum) with an overall Grms level of 0.53 (see below). The theorefical stroke required to run this vibrafiun profile is 47.12 mm (1.855 in) peak to peak:
