Title: Numerical Investigation of the Effect of Road Random Excitations on a Transport Unit
Keywords: vehicle modelling, road surface, spectral density, random vibrations
Abstract: In this paper, the mechanical-mathematical model of a transport unit was investigated, using statistical dynamics methods. The road surface irregularities are present like a random function. The input parameter is spectral density of road surface. The results from the numerical experiments show the displacement and acceleration spectral density of the sprung and unsprung masses of the transport unit.
