Studied and Their Application of Vibration Control Technologies
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.
