| Abstract: | This paper studies the vibration of the elastic pipes conveying fluid, which are widely used in the petroleum,chemical and nuclear engineering as a kind of important structure element.By using Harmilton's principle and Euler's theory of elastic beam and taking Coriolis force of fluid into consideration,this paper builds the mathematical model for the problem on free vibration of elastic pipe conveying fluid,employs the Galerkin approach to find solutions to the model,analyzes the solutions and obtains corresponding conclusions. |
