A new development in the numerical description of road profile realisations

International Journal of Vehicle Design (IJVD), Vol. 34, No. 2, 2004

Abstract: The well-known procedures to road profile simulations in general use the real coherence function γ instead of the complex cross spectra, consequently the simulated autospectrum function and standard deviation approach only the target ones. In this paper, the above-mentioned procedures are improved by the consideration of the nature of these cross-spectral characteristics. As a result, the simulated tracks computed by the improved procedure represent exactly the target standard deviation and autospectrum function. The applicability and effectiveness of the discussed procedure will be demonstrated by the analysis of measured data of a Hungarian highway.
