The road pavement surface is not a perfect plane, it includes irregularities that can be singular or distributed. The latter are always present in every pavement surface. They are due to the unavoidable defects in the road construction process and to the progressive degradation of the materials and of the structural capacity of the pavement. Vehicles moving onto the road surface are dynamically excited by the variations of the elevations of road profile and, as a result of this, vibrations are transmitted by vehicle body to car occupants. The discomfort drivers fell due to these vibrations is one of the key factors in the speed perception. The difference with real situations can induce higher speed in driving simulators. The TEST laboratory has a dynamic driving simulator where a real car is fixed on a 6 degrees of freedom motion platform. It is able to reproduce part of the accelerations the occupants feel, in particular those arising from curves, braking manoeuvres, pavement surface singular irregularities like trenches, potholes, curbs etc. A team of researchers from University of Naples “Federico II”, Second University of Naples, University of Cassino and the Oktal Company have improved the system allowing the implementation of the vibrations due to distributed irregularities. In this paper the experimental module set up and the results of the first experimentation carried out will be described. The outcomes of the tests show a real influence of the magnitude of the irregularities on the behaviour of the subjects driving the simulator |
