ABSTRACT:

In this paper we analyze both theoretical and experimental aspects in relation with the rubber pieces compression, pieces that are also isolating the vibrations and noises made by the machine engine. In the first part we make a discusion about the vibrations made by the engine and about the influence of the vibrations on the rubber pieces, which are a support for the engine. In the second part of the paper we analyze the experimental part in which the rubber piece (engine support) is constrained to compression on a special stand in conditions which are closed to the conditions from the real exploitation.
