FLORES MORENO, Raudel et al. Analysis the tires for finite element to determination coefficient of dynamics loads in structures of agricultural machines. Rev Cie Téc Agr [online]. 2010, vol.19, n.4, pp.10-16. ISSN 2071-0054.

The incorrect determination of the dynamic load coefficient, are joint to other difficulties related to the over dimensioned of the parts, which produce and excess of weight and additional expense. In the agricultural machines is of great importance the study of the shock systems, due to the fact that they are able to absorb the impact load decreasing in this way the affectations that produce on the structures. In the present Work approach mainly methods of calculation by means of Assisted Design by Computer and finite element analysis for determination dynamic load coefficient with presence of shock elements how the typical tires of agricultural machine. An evaluation of the model, use finite element analysis combines with traditional calculation methods of dynamic load coefficient, during an impact cause in back beam of agricultural trailer leaning on tires, subjected to an abrupt fall of a height of 5 cm, throw a decrease of 17,54% in the tensions in the danger point of the structure, product of sock action of the tires.

Palabras clave : impact; finite element.
