Simulation of oscillations of composite pipelines conveying pulsating fluid

The article considers the problem of vibrations straight sections pipeline based on theory beams. A mathematical model dynamics a viscoelastic pipe with pulsating fluid is developed. speed assumed to be harmonically fluctuating and has following form: V ( t ) = υ 0 (1 + μ 1 cosϖt ). simplified using Bubnov-Galerkin approach solution set common integro-differential equations time as an independent variable. numerical removal singularity in relaxation kernel integral operator used solve equations. for unknowns was get system algebraic Gauss technique resolve fluid-transporting pipes have difficulties that can solved computationally.
