Dynamic Fluid-structure Interaction Analysis of Water-pipe Systems

Occasionally, very strict vibrational requirements are specified for sensitive equipment used in high-tech facilities, such as radar towers and synchrotron facilities. Various external and internal vibration sources such as traffic, indoor pumps and human activities can have appreciable effect on the vibration levels in such facilities [1]. In the present study, the synchrotron research facility MAX IV, which is currently under construction in Sweden, is used as a numerical example; see Figure 1. Synchrotron light beams, originated from accelerated electrons, will be used for measurements in various research fields such as material science and medicine. The quality of the measurements at MAX IV is depending on the stability of those synchrotron light beams. Strict vibration requirements are therefore set for the facility.
