Notes:
One hydraulic pressure generator has been developed with a unique rotating valve and thewaveform of generated waves is approximately square-like shape under the low rotating speed. Thegenerated wave has advantages for research in the dynamic characteristics of hydraulic components.The unique rotating valve consists of a rotor and stator which have a number of rectangle groovesprecisely milled on the peripheries of the rotor and stator as fluid channels. The rotating rotoralternately switches the fluid channels to open and close state, therefore the waveform is close tosquare in principle. The pressure transient on the generated wave plays a major role and influencesdynamic performances of generated wave. For analyzing the performances of the generator, onesensitivity pressure transducer mounted on the outlet of the generator to measure waveform in timedomain. In addition, through Fourier series expansion the spectrum of generated waves clearlyindicates the harmonic components of generated waves. Results show the waveform is close tosquare-like under the low rotating speed in time domain. In the frequency domain, the spectrum of thegenerated wave demonstrates the bandwidth is abundant. Thus, the generator could be one kind offunction generator to performing the calibration of the hydraulic components
