Paper Abstract

Hydraulic exciting system consisted of pipeline and wave-exciter has been constructed to study hydraulic pipeline vibration control laws. Through controlling the inverter frequency conversion, opening and closing of the shock device produce periodic vibration in hydraulic pipe.The excitation test system is established. The vibration signals on different point of pipeline have been collected and analyzed to come to the law of pipeline vibration. The results show that pipeline vibration frequency decreases with the system pressure increaseing in the same excitation frequency; when frequency and pressure are determined, the vibration waveforms of different point on pipe are the same, almost nonexistent phase differences, but they are inconsistent with amplitudes on different points. Pipe vibration close to the hydraulic cylinder is slightly intenser than that near the wave-exciter.
