As part of this work, the vehicle platform on which the 130 mm caliber artillery tool was integrated was analyzed. The analysis of the platform was performed in the numerical program FEMAP. As it is a fast variable impulsive process, a dynamic analysis was performed. The type of analysis, Direct Transient, allows the determination of various parameters of a structure that is loaded with a force that is variable over time. The platform was analyzed with 2D and 3D finite elements, which show different values of the final results. Analyzing the results leads to the most suitable final element for further analysis. The further course of analysis involves analyzing additional supports on the vehicle platform. Extra supports are placed at different angles about the vertical plane. The analyzed angles are 15°, 45°, and 60°, while the tool is placed at various angles of elevation and direction. Through this analysis, certain laws were observed in the behavior of the construction, and the best variant that could be realized in the future was observed. This is the variant that would be the most suitable in terms of the load on the supports during the action of the weapon. Since the process takes place in a short period, the optimal variant should handle rapid load changes.
