EN The main subject of the work was numerical and experimental dynamic studies of top-hat thin-walled elements joined by spot welding. Spot weld diameter and pitch distance were the main parameters describing geometrical shape of examined elements as well as the material they were made of. The main purpose of the carried out investigations was to determine the spot weld pitch distance and diameter influence on thin-walled elements deformation as well as energy absorption capability. The results enabled determination of high-grade spot welds execution technology and fuli utilization of thin-walled elements energy absorption ability. The analysis of joining technique influence the longitudinal beam deformation manner as well as dynamic energy absorption was executed. Moreover the analysis of materials energy absorption application was carried out. High strength steels, the most often used in the automotive industry, were chosen for the energy absorption elements and load-carrying structure application. Realized experimental tests enabled the verification of elaborated top-hat profiles discrete models for various materials, spot weld diameters and pitch distances. The comparison analysis of the acquired experimental and numerical results was carried out. The obtained outcome may be utilized during the energy absorption elements design and the elaborated discrete models building methodology can be used in preliminary project works, where one has planned numerical simulations of load-carrying structures crash loadings.
