Abstract

An efficient approach to determining dangerous relations between design parameters for a submerged pipeline transport system with the most frequently used tandem position of tubes (one after another downstream) intended to ensure accident-free operation of the structure under consideration is presented. To solve this problem, the effect of the particular position of pipelines on the character of their dynamic response is analyzed. For this purpose, the hydrodynamic mechanisms of pipe vibration excitation are considered first, because they significantly influence the strength of the structure. Based on the analysis of the numerical and experimental results of studying the pipeline behavior in a fluid or gas flow, a technique is developed for determining the inappropriate values of the amplitude of pipe vibrations and providing safe operation of such tubular structures. The proposed model of the numerical experiment is applicable for complete reproduction of all excitation mechanisms known for tube bundles, namely, the periodic vortex separation and the hydroelastic excitation.
