Experimental Study on Parametric Resonance of Fluid Pipelines
摘要
Abstract
The technique of non-contact vibration measurement was applied to the experimental investigation of parametric resonance of a fluid pipeline with both ends clamped under pulsating flow excitation. The experimental platform has a nice function for control of flow velocity, pulsation frequency and pulsation amplitude. The technique of laser vibration measurement was employed to obtain the information of the pipeline’s vibration. Based on the results of several sets of experiments, the regions of 1/2 sub-harmonic parametric resonance of the first modal of the pipeline were determined. The results were qualitatively consistent with those of the theoretical calculation.关键词
