Selected examples of referring the examined stochastic technical stability to the ISO standards

Jerzy Kisilowski, Jarosław Zalewski
In this paper, certain examples of comparison between the selected definition of the stochastic
technical stability (for motor vehicle models) and the ISO definitions (developed for real
vehicles) have been discussed. Being able to refer the examined stability of a mathematical
model to the real object may result in verifying the properties of the latter on the basis
of model tests, instead of the field trials. Such an attempt has been presented previously,
but in a more general approach. The aim of this paper is to present a certain attempt to
compare the results obtained for a simulated vehicle model in virtual environment with the
specific definitions of stability dedicated to the real motor vehicles. The background of this
considerations liesin the examination of the stochastic technical stability, which allows any
mechanical system undergo external random disturbances, such as road irregularities.
