An analysis of the impact of road conditions on the stochastic technical stability of a motor vehicle mathematical model was prepared, with additional, non-uniform load, and for the necessity to change lanes due to eg. bypassing obstacles or overtaking. The simulation was performed for adverse road conditions at randomly occurring surface unevenness.
Research was based on a motion simulation of a vehicle model at a speed of 100km/h, enabling analysis of the influence of both the mass – inertia parameters and the road surface conditions. Two cases were considered: the motion on a flat and icy and an uneven and icy road. Simulation of a mathematical model of a sports vehicle was prepared in an MSC Adams/Car environment. The considered model included non-linear characteristics of its flexible elements.
Presented results can also be used as one of the series of experiments proving the versatility of the discussed method, not only for the road vehicles.
