Ordinarily we would just use a servo valve and LabView to generate the waveform. The problem is the frequency of the superimposed waveform. I can't find a servo that will act that fast. The test doesn't require flow and essentially all the lines would be "fluid-solid" and therefore the pulse...
I have a requirement to test a hydraulic filter assembly 280,000 pressure cycles with pressure from zero (0) to 300 psi and back to zero (0) at a rate of 10 to 25 Hz with a superimpose impulse cycle of zero (0) to 90 psi and back to zero (0) at a rate of 210 Hz. A representative image would...
