Keywords: pipeline vibration, numerical solution, pressure riples, three dimensional model

In the paper numerical solution schemes have been developed to analyze the pipeline vibration under acoustic excitation due to pressure ripples in transporting fluid. To predict high-frequency pipeline response the three-dimensional model is created. To reduce calculation costs of 3-D model the complex model of pipeline vibration is formulated.
