Influence of Composite Neoprene upon the Energy Internal Dissipation in case of Harmonic Process
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2009, Vol 6, Issue 2
Abstract
This paper presents the approach performed on viscoelastic systems with such geometrical configuration determining the behaviour as composite neoprene, tested under dynamic regime in two distinct cases, as follows: - system having kinematical excitation and constant amplitude and - system having dynamic excitation under inertial regime for the perturbing force generation. Basing on both the dynamic response analysis and the dissipated energy inside the viscous element and assembly, it results in evaluation of the mechanical work in two different ways as a function of the exciting system parameters as well as the viscous force parameter. This paper shows the different performance ways of the dissipated mechanical work depending on both the kinematical parameter changing (pulsation, amplitude) and the viscous damping factor.
