Fluid-Induced Vibration of a Hydraulic Pipeline with Piezoelectric Active Constrained Layer-Damping Materials

The basic structure of a pipeline is complex due to the narrow installation space system. Thus, considerable number pipelines are adopted in When hydraulic works, it impacted by fluid, which produces vibration. It necessary implement an effective method control vibration In recent years, research on active constrained layer damping (ACLD) technology increasing. However, there few studies characteristics ACLD system conveying fluid. and fluid studied this paper. Considered influence fluid–structure interaction, motion equations can be derived, finite element model established based treatment. effect elasticity modulus, thickness viscoelastic layer, length position patch, velocity pressure voltage for all considered. results show that has great pipeline.
