Abstract

Abstract

By using generalized Duhamel's integral and integral transform, this paper investigates random response of an infinite beam on the Kelvin viscoelastic foundation subjected to a moving load. It's found that displacement response of the beam is a non stationary random process even if the moving load is a stationary process. The follow up coordinate system is established to make the displacement became a stationary random process.
