Coupling Vibration Analysis of Piezoelectric Laminated Rotating Cantilever Pipe Conveying Fluid

Abstract

This paper focuses on the flow-induced vibration characteristics involving electro-fluid-structure coupling in rotating cantilevered pipes with a piezoelectric material layer. A dynamic coupling mathematical model for a cantilever rotating pipe with a piezoelectric layer is constructed based on Hamilton’s principle, taking into account the effects of the cantilever pipe’s rotational speed and the piezoelectric material properties. The resulting governing equations are solved using the Galerkin method. The findings demonstrate that the system’s vibration characteristics are significantly influenced by the rotational speed as well as piezoelectric parameters like voltage and resistive load.
