INFLUENCE OF KINEMATIC PARAMETERS ON THE DETERMINISTIC VIBRATIONS OF THE VISCOELASTIC LINEAR CONNECTING ROD: PART OF A ROD LUG MECHANISM

In (Bagnartt & Marghitu, 2000) we obtained the mathematic model of the vibrations of a kinematic element, with viscoelastic linear behaviour, in parallel plan movement. Starting from this mathematic model, on the basis of Alfrey and Lee analogy, we present in the form of a matrix, a mathematic model in first approximation of the vibrations of the viscoelastic linear connecting rod of a mechanism connecting rod lug (Fu et al., 1997). We solve this model with the aid of integral transforms, the resulting solution having the form of a series. In a concrete numerical case, we compare this solution with the experimentally obtained displacements.
