Comparative evaluation of the results of computer simulation and strength tests of the frame of a light commercial vehicle

The aim of this work is to justify the use of developed finite element models to assess the strength and stiffness of structures being designed and developed. For this purpose, it is necessary to compare the results of computer simulation and strength tests. In this article, the numerical results obtained by using a finite element model of the frame of a light commercial vehicle are validated for the first time. The finite element model is distinguished by the representation of particular frame elements and their joints. The comparison of stresses at characteristic points of the frame, as well as its movements and twist angles, confirmed a satisfactory convergence of the results of calculations and experiments. It was concluded that such models are adequate and can be used by design engineers at automobile enterprises.
