This paper presents a methodology for modelling riveted truss-joints within the carrying structure of the working organ of a rotating excavator. The paper illustrates a real model of the most loaded truss-joint with its overall complexity, as well as its finite element model, introducing simplifications in order to analyze the truss-joint by using a computer and a suitable software package. The finite element model (FE model) keeps all the features of the geometrical shaping of the truss-joint, introducing a methodology which brings the features of the real model in conformity with the finite element model. The purpose of truss-joint finite element modelling enables a local analysis of the deformations and stresses at the truss-joint's steel plate exposed to outside loads' impact. Hence, the paper also defines a methodology for modelling loads at the truss-joint, the static ones when the excavator is out of work, and the dynamical ones within typical working regimes.
