Abstract

Abstract

The fatigue analysis for a whole pipeline system is rather rare to date, while in this paper, we accomplished an integrated computational fatigue analysis of the pipeline system based on model constructing and fluid-solid coupling by using Workbench and nCode DesignLife method.And the high pressure industrial water pipeline is studied under normal interior flow velocity and high working pressure conditions respectively.The fatigue response of the system and individual part is affected by various inlet velocities and random excitation forces.The results indicate that the interior flow velocity of each part in industrial high-pressure pipeline should be monitored for the system health.The fatigue failures generally occur on the connecting parts, especially at the interior intersecting line segments.Piping system can extend the fatigue life of flanged pipe at extreme states.This work provides a significant reference for the design of the high pressure industrial piping system in preventing the fatigue failure.
