“…Many engineering systems, such as power conveyor belts, magnetic tapes, textile fibers, aerial cableways, high-rise elevator cables, aerospace vehicles, etc., can be modeled as axial motion structures under appropriate assumptions [1][2] . Therefore, the study of the vibration of axially moving structures has important engineering application value.…”

Axially Moving Beams can serve as simplified models for many engineering systems, such as aerial cable trams, power conveyor belts, magnetic tapes, textile fibers, aerospace vehicles, etc. They often work in open environments in the wild, with random excitations. In engineering practice, viscoelastic materials are widely used in various engineering fields. This article studies the lateral random response of axially moving viscoelastic beams under various random excitations. Under the random external excitation of concentrated and distributed loading, analytical expressions of the mean function, correlation function, power spectral density, and mean square function of the random response of an axially moving viscoelastic beam are derived. They prove the correctness and simplicity of the Pseudo-excitation method for solving the power spectral density of the random displacement response of axially moving viscoelastic beams.
