In-Plane and Out-of-Plane Vibration Analysis of Uniformly Curved Pipes Conveying Fluid

내부 유동이 있는 곡선 파이프의 면내 및 면외 진동 해석

The non-linear differential equations of motion of a fluid conveying curved pipe are derived by making use of Hamiltonian approach. The extensible dynamics of the pipe is based on the Euler-Bernoulli beam theory. Some significant differences between linear and nonlinear equations and the basic analysis results are discussed. Using eigenfrequency analysis, it can be shown that the natural frequencies are changed with flow velocity.
