The significance of the presence of a trailer attached to a vehicle was illustrated in this contribution through analysis of the directional stability of the vehicle-trailer system. We presented an approach utilizing the MBS modelling of a vehicle-trailer system dynamics. Several simulations of the vehicle-trailer system were made with the MBS computer codes and dynamic responses were compared against measurement results for verification. Such codes enable us to carry out evaluations of situations not generally executable because of the threat of damage to researchers and the equipment.

COBISS.SI-ID: 11610139The paper describes a system for constant monitoring of roadway surface temperature in order to optimise the parameters of applying freezing-prevention agents. The system consists of sensorics, software for data acquisition and transfer and a server for data storage and monitoring. The data about roadway surface parameters is monitored almost-on-the-fly. The data history can be used to direct winter service vehicles to the critical roadway sections, and to reduce oversalting in less exposed sections. Possibilities of employing the system and its further development are discussed in conclusion.

COBISS.SI-ID: 11363867Design considerations of vertical velocity-reducing features are discussed. A measurement vehicle with sensorics has been set-up and used on several existing features on public roads. A software application for interactive driving simulation has been used to simulate driving over the selected types of features. The simulation results are compared to measured data. The results are discussed from the traffic safety and the suitability point of view. The conclusions assess the applicability of driving dynamics simulation in evaluation and design of velocity-reducing road features.

COBISS.SI-ID: 11415067The paper presents the benefit of taking account of the yield-point phenomenon in constitutive models of cyclic plasticity when evaluating the development of a multiaxial stress-strain state and accumulated plastic strain of the surface-hardened raceway of a large-dimension rolling bearing. The results indicate that taking account of the yield-point phenomenon results in a reduction of the evaluated plastic strain size, while simulated growth of plastic strain accumulation is much faster.

COBISS.SI-ID: 11447323Upon the invitation of the organizers and funding participation in the conference by the U.S. Office of Naval Research Global, the benefits of the description of the yield-point phenomenon in constitutive models of cyclic plasticity has been presented. The presented results confirm not only the adequacy of the model but also appropriate and necessary to use the description for predicting low cycle fatigue life of the real structural elements made of materials which exhibit the yield point phenomenon.
