EVALUATION OF THE ENERGETIC PARAMETERS OF VISCOUS DISSIPATION FOR DYNAMIC SYSTEMS EXCITED IN HARMONIC REGIME

Oana TONCIU, Polidor BRATU

Abstract


The technological equipments with vibrating action, the anti-seismic devices in the structure of bridges or buildings for base isolation, are evaluated based on the concept of functional performance and length of service behaviour. In this paper, is presented the evaluation of the energy dissipation level based on the linear viscous damping elements. The linear viscous damping can be a viscous shock as part of the internal structure of a deformable material with linear viscoelastic behaviour (elastomers, soils, plastics, composites) as well as in the form of added constructive. The studies are highlighted a linear dissipative behaviour in the engineering fields of interest with the option of evaluating the dissipated energy and the dissipative power of the materials in operation (soils, asphalt mixtures, concrete).
