Analysis of loads on the structural elements of the forest machine during stopping

Abstract

To ensure sufficient longitudinal stability, uniform distribution of gravity over the supporting surface of the tracks and, therefore, creating a lower specific pressure on the ground, the loader's cargo travel is carried out with the boom in the vertical position, which causes significant loads when the machine is stopped with a load. The article presents the results of modeling the dynamics of loads on the working equipment and the body of the logger in the stop mode, taking into account the influence of operating factors. The accuracy of the results depends on the completeness of accounting for factors affecting the operation of the machine and, therefore, on the loading of the structural elements of the machine. However, the desire to fully cover the factors leads to the need to draw up a large number of equations, which complicates the mathematical apparatus and negatively affects the accuracy of the results. Therefore, when compiling equivalent dynamic systems, only the most important factors should be taken into account, which makes it possible to simplify mathematical models without sacrificing the accuracy of the data obtained.
