A complete dynamic model is realized for a vehicle on wheels with tyres, which wheels are rigidly tied to the chassis of the car. The tyres are considered elastic elements, having characteristics of the sticky and hysteretic redumption. A dynamic model is realized and permits the establishment of the chassis’s movement of the equipment on the vertical direction and the rocky and ruliu movement, as a result of the vertical dislevement of the rolling track. It is realized an analytic model for the cinematic movement of the equipment by the rolling track. There are obtained analytic solutions for the strained vibrations produced on the equipment by the cinematic movement produced by the rolling track, modeled as a harmonic function.

Epoxy resins possess enhanced mechanical, chemical and physical properties, i.e. increased shear and compression strength, resistance in solvents, as well as at high temperatures.In the present paper, two-components of epoxy resin were tested through a developed experimental apparatus, applying tensile stress loads. Rolls and aluminum pipes, as well as further specimens were used. The specimens were cemented under constant temperature and humidity conditions. The experimental results were simulated with the aid of FEM-based procedures. The stress–strain curves of epoxy resins derived from previous works, were considered. The results revealed that the resins fail mainly due to poor adhesion with the cemented surfaces and not owing to cohesion release.

Using simple examples from the field of vibrations, it is shown how “continuous space/discrete time” models can be constructed in this formalism. For instance, it is presented an example of a mass-spring system, working dumped in different ways or excited. In the end of the paper conclusions regarding the SCICOS program are formulated The Annals of ''Dunarea de Jos'' University of Galati : Fascicle XIV MECHANICAL ENGINEERING, ISSN 1224 - 5615 2005-01-01T00:00:00Z
