HX-V500

The HX-V500 is a multi-axis hexapod for low frequency vibration isolation in 6 degrees of freedom. The payload platform and base platform structures are similar to aircraft construction for light weight and structural stiffness. The standard HX-V500 is basically passive except for a small amount of air supply (1 SCFM) required for operating the isolators. The HX-V500 can be operated on a compressed air bottle for a limited time allowing for completely passive operation. Download the HX-V500 datasheet for more detailed information.

Watch a video illustrating the isolation performance. For the video, the entire hexapod is mounted on 4 air bags, and an electrodynamic shaker provides input disturbances to the base. Laser pointers attached to the base and payload platforms illustrate the isolation performance.

Standard Models
Isolated degrees of freedom	6 (3 translations and 3 rotations)
Vertical plunge frequency	As low as 0.8 Hz (payload-dependent)
Max. payload weight	500 lbs.
Max. payload height	Approximately 4 ft.
Max. payload width	30 in.
Max. payload depth	30 in.
Vertical isolation performance	50 dB at 40 Hz
Horizontal isolation performance	50 dB at 40 Hz
Facilities required	1 SCFM at 110 psi dried air

Frequency (Hz)	dB Attenuation
1	0
2	1.5
5	7.8
10	10.6
20	20.6
30	32.1
40	50.6
50	48.2

Note that the large dip in the No isolation curve is due to a test fixture mode.

for vertical and horizontal motions

1	2.086	0.877
2	0.596	0.428
5	0.113	0.123
10	0.093	0.029

Why consider the HX-V500 over traditional methods of isolation?

Isolation Method	Problem
Mechanical springs	For 1 Hz isolation, 10 inches of sag would be required.
Air bags	Flexible sidewalls add significant friction effects making them useless for low-frequency vibration isolation. Difficult to obtain engineering data such as lateral stiffness.
Elastomers	Possess temperature-dependent properties. Variation in properties among production batches.

Complete Hexapod System

If you�d like a turn-key system, an oil-free air compressor with a built-in dryer is available and can be mounted on a rolling chassis if desired. This compressor/dryer system operates on 110VAC power (60 Hz) and provides more than adequate air supply for operation of the HX-V500.
