Damping prediction of particle dampers for structures under forced vibration using effective fields

Abstract Particle damping is a promising technique for variety of technical applications. However, their non-linear behavior and multitude influence parameters, hinder currently its wide practical use. So far, most researchers focus either on determining the energy dissipation inside damper or overall when coupled to structure. Indeed, almost no knowledge exchange between both approaches occurs. Here, bridge build combine techniques systems under forced vibrations by coupling field effective particle mass with reduced model vibrating Thus, structure estimated very quickly. This combination essential an efficient dimensioning process also provides deeper understanding dynamical processes. The accuracy proposed method demonstrated via simple application example. Hereby, are analyzed large excitation range first using shaker setup. exhibits multiple areas different efficiency. underlying modeled FEM modal reduction techniques.
