Comparison between Vibrations Transversal Displacements Analytic Determined for a Linear Elastic Connecting Rod and a Linear Viscoelastic one (After the Validation by Experiment of the Vibrations Effective Accelerations)

摘要

This work presents the comparison between vibrations transversal displacements analytic determined for a cinematic element of a crank and connecting rod assembly with linear elastic behaviour comportment and one with linear viscoelastic behaviour, considered in free vibrations and after the corresponding effective accelerations of vibrations were validated by experiment. The movement equations of the straight cinematic elements in plan-parallel motion are obtained by using the Hamilton's variational principle. In order to obtain the dynamic response, the Laplace integral transforms and the finite Fourier transforms are applied.
