Abstract

The study of issues related to the research of the soil's state on the surface of the most constant technological track is relevant, since the movement of running wheels along narrow tracks determines the traction and coupling properties of the machine-tractor units, their vibrations, the stability of movement and the controllability of movement. The рurpose of this study was to increase the efficiency of the process of profiling the microroughnesses of the soil surface located in areas that form a track along which the running wheels of machine-tractor units will move, by substantiating a new scheme of an automated profilograph and developing methods for its use. For this study, modern methods of experimental researches based on IT technologies were used. In particular, an automated complex has been developed for measuring and evaluating the microprofile of soil surface irregularities on the very track of the tramline. The results of experimental studies in this matter have shown that the standard deviation of the soil surface irregularities reaches ±0.84 cm. This gives reason to consider the harmonic components of these functions as damped, having normalized correlation functions. The graphs constructed using PC have showed that most of the dispersions of soil surface irregularities on the ruts are concentrated in the range of 0…0.3 cm −1 . It has been established that the generator of the formation of irregularities in the longitudinal profile of traces of a permanent technological track acts as parameters of the treads of the wheels of machines moving along it. The obtained results of the study can be used when selecting the protectors of pneumatic tires of the running wheels of machine-tractor units moving on two tracks
