ABSTRACT. This paper presents vibration analysis and mathematical model using Euler-Bernoulli and Hamilton’s energy expressions for fluid conveying welded Galvanized Iron pipe with clamped-clamped boundary condition. A 3D CAD Model was developed in NX-ideas for empty pipe, pipe with fluid flow and welded pipe with fluid flow. Vibration analysis was performed on developed models for 3 mode shapes to generate frequency data using ABAQUS. The developed models were imported in to ABAQUS for generating frequency data. For the welded pipe, effects of weldment at girth welds on the vibration characteristics and stability of pipe was investigated. Results acquired from ABAQUS were compared with theoretical results of natural frequencies and observed the variation of 3% error.

Keywords: clamped-clamped, Euler Bernoulli, fluid conveying pipe, weldment, ABAQUS
