An analytical estimation method is described for lateral vibration of piping system by the pulsation of containing fluid. The vibration of piping is considered as a forced vibration by the fluid force due to the pressure pulsation. The pulsating pressure and flow rate of containing fluid is estimated using the transfer matrix method. The vibration response of piping is then calculated utilizing model parameters of the piping vibration and the fluid force. The estimated responses on the pressure pulsation and piping vibration are compared with measured responses in both model piping system and actual high repsssure pump delivery line and it is found that the presented analytical estimation method has reasonable acculacy for practical use.
