“…The directional cosine matrices between the inertial and non-inertial systems were assumed to be zero-sided. Simulations were conducted by recording the displacements of the wheelset in the direction of the OY axis, determining the frequencies and then the probability of stable motion in the Lyapunov sense [59][60][61][62][63][64][65][66][67][68][69][70][71][72].…”

This article presents a definition of stochastic technical stability that was applied to test a mathematical model of a passenger railroad car crossing a turnout with the speed exceeding 160 km/h. Stability defined in this way allows testing of Lyapunov’s stability with disturbances from the track and for a nonlinear system. The STS test of a nonlinear mathematical model of a passenger car was carried out by perturbing the motion of the mathematical model with irregularities originating from the track gauge change and wheelset motion in the direction transverse to the track axis. The main aim of this paper was to determine the influence of various factors and technical conditions on the assessment of the stability of various means of transport. The analysis presented can be used to assess the dynamics of electric vehicles, whose mechanical parameters differ from those of combustion vehicles at present. The area of stable motion in the Lyapunov sense was defined using the STS method. Simulations were performed to determine the trajectory of the wheelset transverse motion. The probability of finding the wheelset in the stable motion area in relation to the rail for a single-point contact was determined. In practice, this is a one-point contact of the wheel with the rail. Conclusions from the conducted research are presented.

In this paper, the selected phenomena related to a motor vehicle’s motion have been considered based on a computer simulation in MSC Adams/Car. The vehicle’s model performed a turning maneuver with the steering wheel release under different road conditions.All simulations have been performed based on the sports two-seater vehicle’s model, at the initial speed of 70 km/h on the flat and randomly uneven road. This enabled us to observe the selected phenomena along the road long enough to relate them to different aspects of road traffic safety in unusual situations. For uneven road, the same profiles were assumed for the left and the right wheel of the vehicle, with two coefficient values determining the maximum height of these irregularities.
