 note = {A vibration reduction method that involves installing two flexible joints in series has been found to be useful for countermeasures against structure-borne sound in pomp piping system. This technique is very useful compared to the general noise reduction which installs many vibration isolators in the whole system. However, the reduction mechanism of pipe wall vibration has not been completely explained yet. In this study, the simple apparatus having the straight-line piping and silicon tubes is treated, and the reduction of pipe wall vibration by installing flexible joints is verified experimentally and analytically. In addition, the effect of the location of the flexible joints on the pipe vibration modes is examined to consider the vibration reduction mechanism. The numerical analysis results confirm that the vibration redacting effect using two flexible joints is caused by optimizing the vibration mode in the upstream piping and by adjusting the installing position of the second joint.},
