Open publisher page 2 citations

Abstract

There exist coupling vibrations between fluid and pressure pipes.The fluid structure interaction(FSI)in pressure pipes is analyzed.A finite element mathematical model of FSI is establised.The FSI dynamics in straight pressure pipes in different constraints is numerically simulated and analyzed with the FEM software ADINA.At last,the modal analysis is carried out.The numerical simulation results show that the FSI has an important effect on piping system working so as to prove that it is necessary to consider FSI for pressure pipes.
