This study utilizes Abaqus finite element simulation software to establish a finite element model of a straight fluid transport pipeline. The model simulates uniform fluid flow input and analyzes the stress and strain distribution of the pipeline under the condition of fixed horizontal placement at both ends, subjected to fluid flow excitation. Stress-strain contour maps of the pipeline are analyzed, and the results are processed and optimized using FFT for further analysis. In fluid-structure coupling analysis, these metrics collectively provide structural response assessment, evaluating stress, strain, and displacement responses of solid structures under fluid loading. Optimizing structural design enhances performance and durability in fluid environments. The finite element simulation results offer valuable guidance for optimizing the design and devising vibration mitigation strategies for fluid transport pipeline systems.
