Instron flutter fatigue torque testframe and hydraulics
INSTRON flutter fatique torque test-frame and hydraulics
* 75,000 pound thrust and 25,000 pound torque sensor rating
* 3000 and 10,000 psi hydraulics (20hp elctric and 4:1 amplifier)
* Hydraulic positioning cylinders and rod clamps

* ~8178# ~30 by 48 by 144 inches & 2110# 70x45x56" raw
Standing, this unit is nearly 12 feet tall.
This unit is designed to apply both thrust and torque to a test sample and to oscilate both axis to test for fatique or flutter failure. The cylindrical structure hanging down from the top plate is a dual axis force sensor. It measures both thrust and torque. It is about 8" in diameter at the low black ring.
The thrust cylinder is the black and silver unit hanging below the lower plate. Below that is a blue apparatus that provides the torque rotational force.
The image above shows the hydraulic amplifier (lower left on black panel) that generates up to 12,000 psi from the 3000 psi main hydraulic source.
The images below show the LEBOW 6468 dual force sensor that is rated for 75000 pounds of thrust and 25000 pounds of torque.
These images show the torque application mechanism. The image above shows the MOOG servo valve that applies pressure to the torque "motor"
The images below show the top side of the assembly where the shaft comes up from the torque "motor". The key thing to not is the huge tab that sticks out and activates the hydraulic limit valves. Rotation is limited to about 90 degrees.
The label on the torque "motor" shows Ex-Cell-O TOTAC 26R102V OIL 3000 psi.
The image above is the primary Moog Servo solenoid valve on the thrust cylinder. This is what allows the cylinder to oscillate up and down for fatique or flutter testing.
These images show some of the AMINCO 30,000 psi high pressure stainless hydraulic components.
The block below is the control for the Miller Hydraulic Pressure amplifier or intensifier. It is controlled by another Moog solenoid valve.
The Miller pressure amplifier is actually called a model 1172BA8 Booster-Accumulator. It turns 3000 psi of hydraulic pressure into as much as 12,000 psi.
The image above shows that the main thrust cylinder is about 12 inches in overall diameter. The rod comes out both ends of the cylinder and is about 5" diameter. The torque "motor" 2 images down is about 9" in overall diameter.
The images that follow show the detail of the Hydraulic Power Unit with its solenoid valve blocks and accumulators.
The images above are of the motor and pump placards.
The image below shows the main hydraulic pressure gauge. It is a bit fuzzy due to the external Plexiglass shield over it.
We think the 1896 hours respresents the real total running time of the hydraulic power unit.
The placard above is for the hydraulic power unit. We are fairly sure it came with the frame so could be used to track down the factory information on the whole system.
There are a pair of BLH 10,000 PSI pressure sensors on the high pressure side of the hydraulic amplifier.
The image below shows two of the 4 hydraulic clamps that insure the upper plate stays in place.
The image below that shows that they 4 tie rods are about 3.5 inches in diameter.
This might be just what you need for your serious torque and thrust fatique testing application.
