【 摘 要 】

The article presents the design features of subcompact small-capacity racing car of kart class. The issues of the strength of the supporting structure are considered. The main strength characteristics of the material AISI-1020 are presented, which was used in the design of the frame chassis. A conceptual block diagram of a methodology for designing a supporting structure model using engineering analysis methods (finite element modeling) is presented. The analysis of structural strength using ANSYS software is carried out. The rode type finite element model of the frame is presented. The directions of application and values of the resulting loads are determined taking into account the overloads experienced by the pilot in collisions. The boundary conditions and the deformation pattern of the frame structure when applying the deforming forces to the front beam along the longitudinal axis of the car, outside the longitudinal axis of the car and on the lateral truss of the car frame are given. The engineering analysis data show a good coincidence of the modeling results with the experimental data.
