“…The lorry frame design considers among others the power drive-train type [1][2][3]13,16,19,34]. Therefore, the frame design has to ensure sufficient rigidity and be as light as possible [6,24,27,33]. More so, it has to ensure that the centre of gravity of the lorry be as low as possible, which affects the driving stability of the lorry.…”

The lorry frame is the main carrying part of a lorry, composed of several components. These components are connected by joints into one structural unit and it forms the lorry chassis. The contribution of this article is focused on the strength analyses of a backbone frame, which is used on an off-road lorry chassis. Strength analyses are carried out utilising the finite element method. This article presents a created three-dimensional model of the frame and definition of boundary conditions (loads, the definition of degrees of freedom) needed for simulation computations. Results of the numerical calculations are the main parts of this article. Attention is mainly centred on the distribution of stresses of the frame under defined loads and its deformations.

“…The application of multiaxial high-cycle fatigue criteria for analyzing the subsurface rolling contact fatigue of structures working in contact conditions was discussed. Studies by Savkin et al [10] and Jadav et al [11] referred to the fatigue analysis of truck frames under service loads. In turn, dynamic loads resulting from the actual road roughness were considered in the truck frame fatigue analysis by Zehsaz et al [12].…”

Components of transport trucks are subjected to dynamic cyclic loads. The magnitude of these loads depends on road conditions and cargo mass. Cyclic loads can cause fatigue failure at stress levels significantly below the yield strength of the material. When calculating fatigue, it is necessary to determine the actual loads acting on the structure under working conditions. In this study, stanchion displacements of overloaded timber trucks were measured under both static and dynamic loads. For the specified mass of timber, a history of dynamic loads acting on the stanchion was obtained. Then, based on the finite element analysis, stress concentration points were determined within the base material and welded joints of the stanchion. The history of maximum stresses at concentration points was determined. Stress ranges and mean stresses for the load history were calculated using the rainflow fatigue cycle counting method. Repeats to failure were determined on the basis of the Palmgren–Miner cumulative damage rule and the modified Goodman correction for the points with the highest stress level. Experimental investigation of the actual load history of the stanchion of significantly overloaded timber truck allowed to determine the mileage to potential failure.
