Resumo

In this paper, the authors consider the loading of the buggy car system under the most typical loading modes: the mode of approach of the front wheel to the obstacle, the mode of the rear wheel approach to the obstacle, the mode of diagonal loading, as well as the mode of twisting the frame around the longitudinal axis. For the convenience of analysis, the frame of the buggy car is divided into substructures, which, in turn, are divided into zones. For each of the zones of each sub-structure, the bar graph shows the proportion of the perceived load for each type of loading. The presented graphs make it easy to analyze overloaded and underloaded areas. For example, the rods of the upper zone of the rear subframe take a very small load, given the proportion of their volume. The reverse situation is observed in the sidewall region: in this zone much lower load is accounted for by a much smaller volume of material. At the same time, the areas of the floor and the middle perceive a load share, consistent with its volume fraction, which can be considered the optimal indicator of load distribution by volume. In this connection, it is important to note that the presented diagrams of the distribution of medium stresses over zones of substructures can be used as a starting point for optimizing of existing or for developing of such structures “from scratch”. Calculation of the load applied to the substructure was carried out by summing the average stresses on the elements constituting the considered subconstruction. In addition, with the help of the appropriate coefficient, an estimate was made to the correspondence of the proportion of the volume of the zone of a particular subconstruction to the proportion of the load applied to it. This information can then be used to optimize the design or used as a starting point for the design of similar structures. All the presented calculations were performed in the SolidWorks software using the finite element method.
