Abstract

A vehicle traveling along an irregular substrate experiences stresses and acceleration due to its reaction to the ground. If the profile of the substrate is precisely known, however complex it might be, then the vehicle response can be exactly calculated. In practice however, the irregularities of the substrate are often inaccurately known, so that deterministic structural analysis is inapplicable. This study presents a non-probabilistic set-theoretical approach to analyzing uncertainty in vehicle vibrations. The uncertainty in the substrate is described by a set of allowed substrate-profile functions. The analysis of the vehicle response consists in determining the range of variation of performance parameters, as the substrate profile varies over the set of allowed functions.
