description: The object of research in this study is the digital double of the spatial frame. The subject of the study is the ability of the frame not to collapse under its own weight and the weight of the main elements (static calculation), and to withstand dynamic loads (when driving on rough terrain). The purpose of the work is to present a ready-to-build, modified frame for a rally-raid buggy based on the test results. General terms are given and some features of creating frames for buggies are described. A series of static analyses of beam models and models with solid inserts are carried out Four types of simulation of installation on supports are given: the frame rigid fixing in places where the suspension is installed, installation of the frame on all suspension arms, two types of installation on three arms with one of the wheels sagging. The stresses resulting from static calculations that do not exceed the yield strength of the selected steel are analyzed, and additional calculations with solid-state models are performed in the most dangerous places of the frame. Based on static calculations, a modernized version of the frame was created. The enhanced construction was subjected to the same static and additionally dynamic tests. Dynamic analyses include a simplified analysis, which simulates the continuous movement of the wheel on the surface, and a analysis where the possibility of separation, in which the effect of the damping coefficient is further analyzed. The inaccuracies of the beam model were described and the assumptions were made. The maximum stresses in the modified model did not exceed the strength limit. Based on the results obtained, the model is finished and ready for construction.
