摘要：Research on vibration control of pipes conveying fluid has widely practical background and economy significance, because vibration in pipes causes vibration and noise pollution, even pipes damage or machine damages when seriously. Common vibration control technologies and corresponding control theory summarizations are introduced systemically, including passive control technology, active control technology, semi-active control technology, and passive & active integrated technology. These will give a good reference for the concerning issues. Then the practical application and the state-of-the-art of vibration control of pipes conveying fluid at home and abroad are summarized. Pipe was very extensive used in the modern industrial field and playing an extremely important role. Distribution of energy and mechanism of vibration course are reflected accurately by research on pipe vibration considering fluid structure interaction, which was accord with the actual conditions, and its significant to reducing vibration and noise. The pipe conveying fluid is studied in this paper considering the factors such as the work of gravity, the change of liquid pressure and the liquid viscosity. The equations of the lateral and axial motion of the pipe conveying fluid are set up based on the Hamilton's principle considering the condition of fluid structure interaction, poison coupling and friction coupled. Finally the further research lessons of vibration control of pipes conveying fluid are presented. Therefore the theoretical foundation is provided for the further analysis and calculation.
