A global trend in the automotive industry development involves weight reduction and enhancement of bus operational characteristics. When designing the structure, it is essential to make a rational choice of the load-bearing frame structure of the vehicle in order to meet the requirements for its strength and stiffness. When designing a bus frame structure meeting the established requirements, not only strength must be taken into account, but also, the effectiveness of energy absorption in the event of a rollover impact in accordance with UN Regulation No. 66. This can be achieved through topological optimization aimed at obtaining a rational layout of the bus frame load-bearing elements. Optimization under impact loading conditions was carried out using the LS-TaSC program with the explicit LS-DYNA solver in ANSYS Workbench, resulting in a rational bus frame load-bearing structure.
