INTEGRATION OF ADVANCED METHODS AND MODELS IN THE METHODOLOGY OF ENGINEER-ING CALCULATION OF TORSION SHAFTS OF LIGHT ARMORED VEHICLE SUSPENSION SYSTEMS (REVIEW ARTICLE)

The requirements for the tactical and technical characteristics of the suspension systems of light armored vehicles are constantly growing, taking into account the increase in the intensity of their loads. It is necessary to improve the suspension system, in particular the torsion shafts, which are the most responsible and loaded in the suspension system of light armored vehicles. The existing traditional methods of calculating the torsion shafts of the suspension systems of light armored vehicles do not meet modern requirements. Today, there is a contradiction between the real indicators of strength and durability and those that should be provided for light armored vehicles of the new generation, and especially for future ones. In addition, this contradiction is deepened by the lack of in-depth scientific methods and models of the stress-strain state that would adequately reflect the processes and states in the torsion shafts of the suspension systems of light armored vehicles, and would also become the basis for developing measures to increase their strength and durability. The analysis of literaure showed the absence of a systematic connection of structural solutions, technological modes and load conditions in the calculations of torsion shafts of suspension systems of light armored vehicles. The necessity of creating such a system approach in calculations is shown. Conclusions were made about the need to integrate advanced methods and models in a single methodology for calculating torsional shafts of suspension systems of light armored vehicles. The necessity of linking stress-strain state methods with constructive, technological, and operational factors and developing a suitable specialized software-module complex for carrying out relevant research is shown.
