Experimental validation of the component synthesis method for predicting vibration of liquid-filled piping
Abstract
Vibration of piping which can be caused by pulsation of contained liquid are discussed. Accurate prediction of such vibration requires consideration of the effect of pipe motion on fluid oscillation, and of acoustic pressure on pipe walls. Component synthesis is an analytic technique that approximates those interactions by synthesis of plane wave acoustics of the liquid and normal modes analysis of the pipe structure. Results of analysis by component synthesis are compared to solutions of partial differential equations of motion and to experimental observations for two example pipe configurations. Simplifying assumptions common to the two analyses are examined.
