The high speed of the road train, maximum use of tractor power and the variety of transported goods, together with the characteristics of the road surface and the design features of the rolling stock, lead to an increase in dynamic loads. This causes an increase in oscillation processes in the ground-trailer-tractor system, which negatively affects traction and coupling properties, handling, stability, as well as ergonomics and acceleration and braking properties. Therefore, reducing dynamic loads and improving the performance of road trains is an urgent task. The study of tractor movement parameters, taking into account the factors and relationships between individual elements, is a complex task, the solution of which, using an effective design model, will improve the consideration of the movement parameters of a transport and technological train. The relevance of the work lies in the fact that when a road train moves on different road surfaces and off-road, the tyre - car - driver system acts as an oscillatory system. Based on the general aim of the study, the purpose of the modelling was to investigate the influence of the design parameters of the coupling device on the braking dynamics of a road train using an electronic model. Based on the theoretical analysis of the braking dynamics of a road train and the analysis of numerous works, it can be concluded that the most acceptable traction devices for use in the operation of vehicles are combined traction devices.

摘要

The high speed of the road train, maximum use of tractor power and the variety of transported goods, together with the characteristics of the road surface and the design features of the rolling stock, lead to an increase in dynamic loads. This causes an increase in oscillation processes in the ground-trailer-tractor system, which negatively affects traction and coupling properties, handling, stability, as well as ergonomics and acceleration and braking properties. Therefore, reducing dynamic loads and improving the performance of road trains is an urgent task. The study of tractor movement parameters, taking into account the factors and relationships between individual elements, is a complex task, the solution of which, using an effective design model, will improve the consideration of the movement parameters of a transport and technological train. The relevance of the work lies in the fact that when a road train moves on different road surfaces and off-road, the tyre - car - driver system acts as an oscillatory system. Based on the general aim of the study, the purpose of the modelling was to investigate the influence of the design parameters of the coupling device on the braking dynamics of a road train using an electronic model. Based on the theoretical analysis of the braking dynamics of a road train and the analysis of numerous works, it can be concluded that the most acceptable traction devices for use in the operation of vehicles are combined traction devices.
