Study of Vibrations Influence Upon the Response of Different Materials Raluca Anda Malciu

This monograph used in experimental investigations a crank and connecting rod mechanism with one of the kinematic links made of different materials. The longest link was made of linear viscoelastic material in the first part of the study and the stress and strains were highlighted; the influence of the behavior of this particular type of material above the vibrations of the kinematic element was studied. The second part of the study used a deformable elastic material for the longest link. Moreover this link was subjected to the pressure of the oil from a rectilinear pair during the motion of the mechanism. There were used in experimental investigations different types of oils as lubricants of the rectilinear pair and the vibrations of the elastic kinematic element were studied.
