FUNCTIONAL ADAPTATION IN A GRAIN CARRIER WHEN THE MASS OF TRANSPORTED GRAIN IS UNSTABLE

Abstract

The methodology of functional adaptation of a grain truck by adjusting the speed depending on the density of the transported grain crop is proposed. As a result of studying the functional adaptation of a grain truck with an unstable mass of transported grain, it was found that fluctuations in the grain cargo during transportation significantly affect the stability of the vehicle, especially during maneuvering and braking. When estimating the weight of a grain truck, the density of the transported grain must be taken into account. The volumetric carrying capacity of a grain truck is carefully assessed by establishing a functional dependence on such parameters as nominal carrying capacity, volumetric carrying capacity, body volume, and cargo volume. The dynamic space of grain truck operation is based on a metric state space, each element of which fully determines the state of the system under consideration according to certain functional parameters. If one or more functional parameters of the grain truck are unstable and deviate from their nominal values, the grain truck may lose its functional stability and not perform the functions defined by the regulatory and technical documentation. In such cases, the dynamic operating space is characterised by transfer functions that provide a mathematical basis for analysing the behaviour of the system. During the operation of a grain truck, the task of ensuring its functioning in one of two areas is solved: the area of operation or the area of optimal operation. To ensure that the grain carrier operates in the optimal region, it is necessary to select such nominal values of functional parameters and tolerance fields to ensure the position of the spread and outputs in this region.
