A modern tractor is a complex mechanical system consisting of a large number of elements united into one whole by various types of connections. The relevance of this work lies in the fact that the tire-vehicle-driver system acts as an oscillating system when the tractor train moves on different road surfaces and off-road. At the same time, it must be taken into account that the entire variety of disturbing influences is taken into account by the "double" (dynamic and kinematic) and "two-frequency" nature of excitation. Both are mainly related to the unevenness of the road surface and the imbalance of the rotating and gradually moving masses.
It must be said that almost all research on vibration protection of a person and a transport unit was reduced to the study of high-frequency vibrations. However, along with high-frequency oscillations, low-frequency oscillations have a significant impact on the human operator and the transport unit.
The study of any oscillating system includes two stages:
1. Study of disturbing influences.
2. Study of vibration dampers.
The study of disturbing influences is mainly reduced to the study of the interaction of the micro-profile of the road and the drivers of the transport unit, to the mathematical description of the road profile and, at the same time, the mathematical description of the laws of change in the relative movement of the driver. It should be noted that the impact on the studied indicators of the road body and the laws of motion is given by the speed of movement, since the frequency and amplitude properties of the influences change. The state of the road, in turn, affects the traction forces, the nature of the interaction between the road surface and the driver in terms of power.
Thus, taking into account the peculiarities of the study of the road-tyre-vehicle-driver oscillatory system, in order to determine the influence of the traffic parameters of the transport-technological train and the characteristics of the road background on the performance indicators of the transport-technological train in general and the operator in particular, it is necessary to draw up a system of differential equations that describes the movement of the transport-technological train taking into account the type of traction-towing device used.
