• Experimental Study on a Curved Pipe Vibration due to Pulsating Flow

抄録

The main purpose of this paper is to investigate theoretically and experimentally nonlinear vibration of a curved pipe, which is excited by the pulsating component of an internal flow. It is assumed that the upstream and downstream ends of the pipe are clamped, and the pipe is inextensible as shown in Fig.1. The equation governing to in-plane motion of a curved pipe, is derived under the assumption that an internal flow is one dimensional and incompressible. Furthermore, the experiment is conducted with the silicon rubber pipe conveying water. The spatial displacements of the flexible pipe are measured by the image-processing system that can perform measurements of the marker in three-dimensional space, based on images from two CCD cameras.
